Most people I know who have an iPad 1 complain that speed is an issue. The iPad 2 certainly fixes that, but Apple's have focussed a lot on optimization and their stack is all built around compiled code.
To me that suggests that tablet performance is only just adequate today.
If we want to realize the dream of a truly open, programmable-on-the-device tablet, we're going to need it to burn some cycles on languages that aren't as efficient as C, and frameworks that haven't been as tuned as iOS.

I think power is very much an issue.
