cheap Android tablets have the main drawbacks of speed (slower, less expensive CPUs) and usually come with older Android versions (1.5 and the like), plus not all have the ability to install apps from the Android marketplace. That doesn’t mean you can’t browse some websites, read eBooks, listen to some music and watch videos on them, all at a very reasonable cost.

Alternative to Aakash Tablet there are
Domo Slate N8 priced at Rs. 4500,
DOMO Slate N9 priced at Rs. 6990 and
