As the rest of the world raves about 10-inch tablet PCs from Samsung and Apple, Indian vendors seem to be betting on cheaper 7-inch tablet PCs to lure buyers.

But these tablet PCs have begun to crowd retail shelves, with a new model being launched every month.

The most distinguishing feature of these low-cost tablet PCs is that they can make calls, a feature that an iPad or a Galaxy tab does not have. 

If you are in the market to equip yourself with a tablet PC that won't compromise on its ability to make voice calls, here's what you can get.

Beetel Magiq: Price: Rs 9,000

This might look like a poor cousin of what you may have seen of tablet PCs but it can connect you to the web, run websites with Flash, stream video and data for a good five to six hours.

And it costs a fraction of what an iPad retails at.

Airtel's Beetel Magiq tablet PC is an Android device powered with a 1GHz Snapdragon processor, packs a 2-megapixel camera at the back and a VGA camera in front for video calling, gives you 8 GB of internal storage and sports a 7-inch touchscreen display.

The touch experience, thanks to the resistive display, can be a disappointing one, especially when you have to wipe your fingers several times over an icon to get it running.

But with a little practice you will know exactly how hard you should press the touchscreen to get the apps running.
There's also nothing visually appealing about a display that delivers resolution of just 800 x 480 pixels (almost what a smartphone's 4-inch display would render).

The 2200 mAh battery ensures that the device is juiced up to six hours of usage.

But this could vary if you run data extensive apps or 3G networks.

There is a docking port and a microSD slot at the bottom of the device.

This docking stand is meant to be used while watching videos, but really it's quite useless.

While Android devices get updated software versions every month or so, Beetel chose to load the older Android 2.2 Froyo OS on this device that is not meant for tablet PCs.

The company has not indicated how users who wish to upgrade their tablet OS can  do so.

What keeps the Magiq tablet PC in the game is the fact that it can be powered with a 3G connection from any network besides Airtel in India.
