Double Power - D7015 7-inch tablet
Many students want a tablet to replace bulkier laptops while on the move, but sometimes its simply not possible to fork out for an iPad or Samsung Galaxy Tab. However, for basic functionality and Internet access in a lightweight casing, there are a number of cheaper options on the market -- such as the D7015 7-inch tablet. It's a little more than $50, but about as cheap as you can get for a tablet at the moment -- and comes with enough basic functions to keep a student happy.
The tablet has 4GB storage space, a processing speed of 1.2GHz, 512mb memory, one SD slot, a front-facing webcam and runs on Android. If you want to go slightly upmarket, consider a Google Nexus.
