This $99 Archos tablet runs Froyo and has a 7-inch 800 x 480 pixel resistive touchscreen and 4 amazing GB of storage. No mention of processor but I suspect a few TI-81s have sacrificed their lives to be part of this mess.
Buying cheap electronics, tablets in particular, is akin to buying cut-rate toilet paper. You realize, at first use, that you made a terrible mistake. Luckily, bad toilet paper doesn’t cost $99 so you can afford to buy a few rolls to learn the truth, but please buy a used Honeycomb device and eschew this garbage completely.
