Time for something a little different now. HP Store is currently offering the HP Slate 10 HD for £169, with 250MB of monthly data for two years. Better still, using code 4OFFHP, you can bring the price down to £162.24. Lovely.
HP Slate 10 HD specs include a dual-core processor, 10in HD display (800 x 1280), 16GB internal storage (augmentable via microSD), and 5MP/2MP cameras.
