The one I like the most had a 7"(1024x600) capacitive touchscreen, microSD card slot, 2 cameras, and it was running the latest version of Android (4.0 Ice Cream Sandwich) on that A10 chipset (1.2GHz CPU + 400MHz Mali GPU). You can see it about 4:10 in.
If I ever get the chance, that will be my next tablet. I know that I have trumpeted the A10 chipset before, but it offers the best value for the price. I have budget tablets on my desk with both a Rockchip 2918 and the Boxchip A10 CPU. In fact, the Polaroid tablet I bought yesterday and the Skytex tablet that I hacked last night could probably stand in for their respective CPUs.
Both run Android 4.0, and the Skytex tablet performs better. Of course, it also currently costs more on the retail market so perhaps I didn't make my point as well as I would have like. But if you compare all the tablets shown in this video I think we'll see a trend. The Boxchip CPU adds a little bit to the price but a lot to the performance.
In any case, all the interesting budget tablets (for the US market) I saw at CES 2012 had the Boxchip A10, not one from Rockchip. The manufacturers certainly think it's the best value.
