I bought an Android Tablet for the Wife for Christmas and have to say for the money it cost its an amazing bit of kit:-
Scroll Excel Android tablet: The world’s cheapest 3D tablet | Electricpig
Its only just been released but won the Gadget Show best bargain tablet award and has been virtually sold out everywhere since, most places seem to be getting stock in again from Mid Jan.
For £130 you really cant go wrong, build quality, screen quality and performace are excellent.
The only snag is that Android Market is not 'officially' supported on this tablet but 5mins and I had it installed and working so its not really an issue.
And no, I'm not related to this product in any way, just really impressed with it...!
