Viewsonic G Tablet is probably the best of the 10" sub-$500 Android tablets out there right now. It's merely decent out of the box, but can be made into a really good gadget with some modding to get rid of Viewsonic's strange proprietary "Tap N Tap" software, and there's a strong community online for doing that. But obviously it doesn't have e-ink capabilities.

They keep hyping this as the year of the Android tablets, saying you should wait until later to buy a tablet, but it just doesn't seem to be happening. Xoom is ridiculously overpriced, Adam is a buggy mess, and other players like Asus have pushed back their release dates yet again.
