Reliance New Tab under 15,000Rs

A new reliance invention‘Yet another tablet under 15K,’ may have been the response from many after the Reliance 3G Tab was announced recently. And yes, like most of the low cost devices entering markets in India, this one too comes from China. Clearly labeled under ZTE, it could make you think and rethink how the company has managed to break the 15K barrier. However, you could simply leave aside the reasoning and read on our review to know if the 3G Tab is yet another cheap tablet or holds within enough features justifying its price tag.

For the price it carries, the Reliance 3G Tab is nowhere near a cheap looking device, we must say. Sporting a decent exterior, it employs a 7-inch TFT capacitive display with multi-touch capabilities. Just below the screen you will find a row of touch buttons (not backlit) – Home, Menu and Back. Scrutinizing the front surface further you’ll also find the light sensor, indicator and VGA front facing camera while the backside shows a mediocre 2MP camera. The edges of the Tab are kept minimalist and uncluttered with speakers, 3.5mm jack, mini USB port, volume control and on/off switch.

It easily slips in hand purses at 389 grams and the look of it could instantly remind you of the Samsung Galaxy Tab. The Reliance unit came with a glossy front side and an easily detachable plasticky backflap disguised in a silver-gray metallic hue. We didn’t attempt breaking it, but the plastic appeared to be pretty fragile. Pulling out the backflap, the Li-Ion battery 3400mAh can be extracted to lay your hands on SIM and microSD card slots. Reliance has also bundled 4GB storage (microSD card) which can be further expanded up to 32GB using the microSD slot. On the inside, it is fuelled with an 800MHz processor and 512MB RAM.

Reliance 3G Tab gleefully employs the Android 2.3.4. So, obviously you get to drool over all the features that Android 2.3 tags along. Now, the inclusion of this version of the operating system is appreciated as there are several smartphones carrying a higher price tag while employing a lower OS version.

This ZTE built tablet has the Reliance mark embossed as soon as you switch it on. You’ll find slight customization with a Reliance skin and annoying welcome tune. Along with the little personalization, you will find the R World Online icon that lets you explore several entertainment facets.

After spending hours indulged into the Fruit Ninja on the iPad 2, the experience on the Reliance Tab was pretty washed off, for obvious reasons. Here, we aren’t complaining or comparing, knowing the price the 3G Tab carries. Besides, we tried our hands on some swiftly downloaded apps, games, live wall papers and the experience was just about fine. The Tab boasts of up to 9 hours talk time and 300 hours of standby, and we feel to a great extent it keeps up to it. With average usage, we managed to stretch it for more than a day.

To sum it up, everyone wants a piece of the tablet and not all can get it due to the high price tags that this device category reads. Moreover, we have a very price sensitive market in India. So, for those looking to get hold of a tablet for usual emails, social networking, exploring Android markets for games and a price tag that reads just Rs. 12,999, then the Reliance 3G Tab would be an option to consider. Further, you must be ready to let go camera abilities and tie down to Reliance 3G plans. On my rating meter it has managed to jump up to 7 out of 10.

Windows 8 Preview - Installation Process

The next big OS from Microsoft is almost ready and we’ve been anticipating its arrival for a while now. So, the final release is still sometime away, from release but the second major preview that was expected early this year is here. MWC 2012 is almost over and Microsoft has gone ahead and opened up the gates for users to download and try out the new platform.

The first open build - the Windows 8 Developer Preview was made available for download in September 2011. The Windows 8 Consumer Preview is a more refined build and is something that should be functional till early 2013. So, let’s quickly look at how to download and install the operating system on your PC. We’ll start by first explaining how to install Windows 8 on a clean system and then, also how to upgrade your Windows 7 operating system to Windows 8 without losing too many settings.

However, before starting, we suggest you backup any important data and applications just in case.

Download Windows 8 Consumer Preview
The first step is of course, to download the operating system. Microsoft has setup a download page from where you can download a tool that will check your hardware and software to see if they’re compatible with Windows 8. If you want more information on the system requirements for Windows 8, head over to one of our news story on the official availability of the preview. The tool then downloads Windows 8 for you. You also have the option to download disc images (ISO images) and burn them on a disc and install it. There are 32-bit and 64-bit builds available on this page. Microsoft has also provided a serial key that can be used to install the operating system.

Burn a copy of Windows 8 on a DVD
Once you’ve downloaded the ISO file, burn it using a disc burning software. If you don’t have one installed, you can always use the default Windows Disc Image Burner that’s part of Windows 7, for example. If you don’t have one, you can download a copy of CDBurnerXP for free. Microsoft offers other options for installing Windows 8 off a USB stick using their USB/DVD tool. Once you’ve chosen how you want to install Windows 8, the process is pretty common and straight forward. In fact, many of the initial steps are similar to Windows 7.

In the case of a clean install, the entire hard drive or at least, one partition ought to be free. Microsoft recommends 16GB of free space if you’re installing the 32-bit version and 20GB if you opt for the 64-bit version.


Setup from an existing Windows installation
If you're doing a clean install of Windows 8, skip this. But assuming that you have Windows already installed, simply insert the burnt DVD and open Windows Explorer. If you have Autorun enabled, the installation setup should start automatically. If it doesn't, double click on the setup.exe in the DVD. The installation will ask you whether you'd like to update the installation before it begins. If you don't want to do this, you can click the Skip button.

Next, enter the product key provided by Microsoft on their download page. The next step is to choose which items from the existing Windows installation you’d like to keep. Choose one of the following and click Next. The user has the option to save Windows settings and personal documents or just personal documents. If you do not want to save anything, you have the option to do that too. The installation will then begin.

Installing using a bootable disc or USB drive
If you’re going to install Windows from a bootable disc, head into the BIOS and switch the DVD or USB drive as the first boot device. If all goes as per plan, you should be prompted to boot through the DVD or USB.

Once you enter the product key, you’re asked to choose whether to install Windows on the entire hard drive or select partition. We recommend using the custom partitioning tool and creating partitions. Select your drive, click on Drive options and choose which partitions you’d like to use for Windows.

We suggest keeping a minimum of 20GB for the 64-bit version but we would suggest making more space in case you’d like to install software on the same partition. Click on Next to start the installation. The files will then start copying to the local hard drive.

Once the files are copied, Windows will reboot and start making final preparations. It’ll then start checking all the devices connected to the system.

Post-install steps
The first step is to enter the PC name and an e-mail address for product updates. This e-mail account will be linked to your Windows account. You'll also be asked to choose some basic settings for Windows. You can choose the Express Settings method.

in the next step, you’ll be asked to enter the password, your name, country and ZIP code. Microsoft also asks for additional information such as your mobile number and an alternate e-mail address for verification reasons. This is also handy in case you lose your password. You’re required to enter at least two bits of information in this step. The last step is to enter your birth date, gender and a text box verification.

Once that’s done, you’ll be able to sign into your all new Windows 8 installation! We'll be covering a sequence of articles on Windows 8, so stay tuned.

Top graphics cards under Rs.15,000 INR

There’s nothing quite like a good ol’ summer vacation, but sadly, all good things must come to an end. We still have about a month before schools and colleges re-open and if you’re back from your summer trip, then here’s how you can occupy yourself till then - gaming! With big titles hitting the PC this summer, you need to be well-equipped to tackle these games, if you want enjoy the experience with all the eye-candy dialed to max. Thankfully, this is easier said and done, thanks to most games being developed for consoles, which makes them running on even modest gaming PCs a sinch. While this has stifled the progress of graphics and effects on the PC a bit, the silver lining here is that even older hardware can easily handle the newer games without having you upgrade every six months. Today, we look at Tech2’s top 5 picks of graphics cards under Rs.15,000 across different price segments.

Sapphire HD 6670 1GB DDR3 - Rs.4,700
We start off with the best card under 5K and this was a bit of head scratcher, since you have two good cards from AMD here - the HD 6670 with GDDR3 memory and the older HD 5670 with GDDR5 memory. The HD 6670 has more shader units, but the GDDR5 memory on HD 5670 has more bandwidth for textures. Now since you won’t be gaming above 1600 x 900 resolution (and we recommend you don’t), we decided to go with the HD 6670, due to the newer architecture and more number of shaders. The higher bandwidth memory comes in handy at higher resolutions, but since this card won't handle games smoothly at such resolutions, it didn’t make sense going for it.

The Sapphire HD 6670 comes with 1GB of GDDR3 memory, their custom cooler, supports DX11 and doesn’t need a 6-pin PCIE power connector.

MSI R6790-PM2D1GD5/OC - Rs.8,400
We now move to the 5K - 10K price bracket, where we have two options for you to choose from, depending on how tight your budget is. Our first pick is MSI’s R6790, which is based on AMD’s HD 6790 chipset. Between this and NVidia’s GTX 550 Ti, which also retails in the same price range, we recommend the AMD card, as it’s faster. MSI has tweaked the card quite a bit and you get a nice overclock right out-of-the-box. The custom cooler should also help keep temperatures in check. With this card, you should be able to game at Full HD resolutions, but just make sure you tone down the eye-candy, especially with newer games. Also make sure you have a good 450W PSU from a reputed brand to start with.

We would also like to give a special mention to the HIS HD 6790, which also retails for the same price as the MSI, but due to the to slower clock speeds, it only needs one PCIE power connector. If you don’t feel like upgrading your PSU, then you might want to get this card instead as it also consumes a bit less power in games.


PowerColor HD 6850 1GB - Rs.9,200
Coming to our second pick in this bracket, we recommend the HD 6850 over the newer HD 7770. AMD’s new HD 7770 is based on the new Cape Verde core, which is derived from the HD 7970 and so, it has slightly better thermal and power numbers. But when it comes to real world performance, it’s either on par or sometimes slower than the older HD 6850, which makes it a bit of a disappointment. Plus, the HD 6850 is also more easily available in the market, since it’s been around for a while.

We’ve gone with PowerColor’s version of the card, since it’s the cheapest in the market and has the same specifications as the slightly more expensive offerings from Sapphire and HIS. The HD 6850 will also run comfortable on a good 450W PSU (like Corsair VX450), but we recommend you get a good 500W PSU at least for some good buffer. This is very capable card and Full HD gaming should be breeze with it.


ZOTAC GTX 560 - Rs.11,000
Coming to the 10K - 15K price bracket, the competition just gets fiercer. We once again have two picks here and the first one is the Nvidia GTX 560. It was either this or the AMD HD 6870, which is also a very good performer but between the two, we picked the Nvidia card for its slight edge in performance. We’ve gone with ZOTAC’s offering here, since it’s one of the cheapest in the market and plus, you get 5 years extended warranty.

MSI N560GTX-Ti M2D1GD5/OC or Sapphire HD 6950 1GB - Rs.14,000
For our final card, we leave the choice up to you. For a little under 15K, we have two very capable cards - the Nvidia GTX 560 Ti and AMD’s HD 6950 1GB. Both are almost identical in performance, with the AMD card being slightly faster in some games. However, the GTX 560 Ti is a very good overclocker, so it easily pushes past the HD 6950 1GB with a little tweaking. It will also run a bit cooler than AMD’s offering.

Samsung Galaxy Note 10.1 preview

The Samsung Galaxy Note 10.1 dispels any doubt about the return of the stylus - the S Pen transforms the tablet into something that will appeal to artist and business types alike. It's a very different experience, one that other tablets cannot match. It's not just the level of precision no finger can provide, the bundled software really extends the functionality.

The tablet itself can be seen as a special edition of the Samsung Galaxy Tab 2 10.1 - the body is slimmer (8.9mm vs. 9.7mm), the chipset is more powerful (both in CPU and GPU terms) and the front-facing camera is much better.
We won't waste too much time comparing the Note 10.1 to the Tab 2 10.1, we'll leave that comparison for the complete review. For now, here's where the Samsung Galaxy Note 10.1 stands.

Samsung Galaxy Note 10.1 at a glance:
Form factor: Tablet
Dimension: 256.7 x 175.3 x 8.9 mm
Weight: 583g
Display: 16M-color 10.1" PLS LCD capacitive touchscreen of WXGA resolution (1280 x 800 pixels)
OS: Android 4.0 Ice Cream Sandwich, TouchWiz UI
Chipset: 1.4 GHz dual-core processor, Mali-400MP, Exynos chipset
Camera: 3.2 MP autofocus camera with 1080p video recording; 2MP front-facing camera
Memory: 16/32/64GB of inbuilt storage, expandable via a microSD card slot
Connectivity: Voice and data connectivity with quad-band GSM/GPRS/EDGE and quad-band (850/900/1900/2100 MHz) UMTS, 21 Mbps HSDPA and HSUPA 5.76 Mbps support, video calls, dual-band Wi-Fi a/b/g/n, Wi-Fi Direct, Assisted GPS, Bluetooth 3.0, 30-pin connector
Battery: 7,000mAh
Misc: Gyro sensor, accelerometer sensor for automatic UI rotation, ambient light sensor, Adobe

Flash Player 11 support, DivX/XviD support, TV-out (adapter required), USB host (via an adapter)
We can only dream of what the Note 10.1 could've been like with a tablet-sized Super AMOLED screen, but the PLS LCD used here offers pretty good image quality too. The 1280x800 resolution is the standard. It isn't much in terms of numbers, but it's perfectly alright in terms of actual image quality.
The tablet runs Android 4.0 Ice Cream Sandwich imbued with TouchWiz magic. The Mini Apps that float around like windows improve the multitasking capabilities. The preloaded Photoshop Touch app is a premium addition. The note taking apps are on the level too - jotting down a memo on the Galaxy Note 10.1 is as easy as on an actual notepad.

Nokia Lumia 900 vs HTC Titan II: Head to head

The two LTE smartphones, which we have on our hands today, couldn't be more different as far as the manufacturer goals and ambitions are concerned. The Nokia Lumia 900 for instance, carries the burden of turning the fortunes for the Finnish giant. The smartphone was launched with an aggressive price tag, and a massive marketing budget. The Nokia offering has no other choice but to succeed.
The HTC Titan II is on the other side of the urgency scale. Being one of the best established players in the Android realm, HTC needs not bet its fortunes on a smartphone, running a less than popular OS. The Titan II does not need to sell in large numbers - the Taiwanese company has the One Series up to this task. Such lack of pressure is sometimes the key to a great product.

This head-to-head feature should hardly be a surprise - after all the LTE sporting Nokia Lumia 900 and the HTC Titan 2 were both announced during CES 2012. The two Windows Phone handsets also hit the AT&T shelves in the same day. All in all, great news in case you are a fan of Windows Phone devices, shopping around for the latest hardware.
Speaking of hardware, you have probably guessed by now, that the HTC Titan II and the Nokia Lumia 900 have quite a few things in common, thanks to Microsoft's strict hardware policy for the mobile platform. Displays and camera units aside, the two smartphone can almost pass for identical twins hardware-wise.
Here's a quick look at what the two flagship wannabes have to offer.
HTC Titan II over Nokia Lumia 900

A slightly faster CPU, clocked at 1.5GHz
Lighter by 13 grams, despite being larger in measures
Larger 4.7" S-LCD screen
16MP camera sensor with various shooting modes
Video recording has a better continuous auto focus
A number of handy, exclusive HTC apps
Equalizer/sound enhancer preinstalled
Nokia Lumia 900 over HTC Titan II
Arguably better design, and more distinctive looks
Polycarbonate unibody and Gorilla Glass covered display will handle abuse better
4.3" AMOLED screen is a better match for Windows Phone OS; has better pixel density too
8MP camera sensor has excellent dynamic range
Costs half as much with a contract
Better battery life performance
Nokia Drive free lifetime navigation out of the box

If looks are main factor, then the Nokia Lumia 900 is likely the favorite here. Its polycarbonate unibody, coupled with a display, sporting infinite contrast levels and punchier colors, looks like nothing else on the U.S. smartphone market. Free navigation from Nokia Drive is a sweet proposition on the software side of things. In a nutshell, there is plenty to like about the newcomer.
The HTC Titan II on the other hand, sports a faster CPU, and weighs less, despite it being larger overall. Its 16MP camera sensor is the biggest you can find on a smartphone in the United States. HTC's exclusive apps add a much needed dash of Sense-d eye candy to an otherwise generic Windows Phone OS look.
