Gizmo works, but it's still a bit behind the feel of Apple equivalent applications. A MC version ported to Android would be nuts. Lots of things you could simply not do on android, compared to PC's. And the work needed to port all relevant features would probably be massive.
I am not totally sure that Android will be the dominant in the market. Perhaps now and for a few years, but I do think that Windows will take back some of the market, and make a good push on tablets and phones with Win8 and coming versions.
I'm looking for a good pad like the new Transformer Prime to come with Windows. I think there is lots that want the same thing, as long as it work well. Preferably with x86 CPU and not ARM. At least in my case. That way I could still run MC on it
