A tablet costing just £30 has launched in the UK, beating off competition from Tesco, Aldi and Argos in terms of price.

The 7-inch UbiSlate 7Ci has 4GB of storage and runs the 2011 Android Ice Cream Sandwich software. The device was originally built for universities and colleges in India and is the latest in a wave of cheaper tablets on the market which has been dominated by Apple’s iPad until relatively recently.
