The LG G-Slate sounds most interesting of these. I'm looking to Chinese tablets to save the day. Many of them are crap, and I suppose that they'll always be a generation behind, but they do start to get better specs. For under $200 (including shipping from China) you can currently get a 1GHz Cortex A8 CPU with 512MB RAM. Only 800x600, resistive touch screen, no GPS... but for the price I think it's decent hardware. I'll be waiting for Android 3.0 to appear on these tablets, so they provide a decent UI.
