Many commentards here seem to be silently assuming that if one purchases one of these cheap-and-cheerful gadgets, then all one's other gadgets must be turned in. The "It doesn't do EVERYTHING..." and assuming that "One must only choose ONE!" as a quasi-religious idiotic fanboi implementation of purchasing gadgets. Daft.
Such a single-gadget approach makes sense when it comes to smartphones, because few people would want to have two phone bills every month (Yikes!). But for wifi-enabled gadgets with no monthly fee, the best approach is to buy one or several of each.
Personally I despise Windows 8's tiled GUI and all it represents, but if someone is flogging a cheap tablet with Win 8, then I'll be in the market for a good deal when they're on sale.
