Ok, now I'm starting to see why Google chose a VM for its OS. I couldn't care less about support for x86 and even MIPS, as ARM was already dominating the mobile chip market, and it has plenty of competition above the ISA level - much more than x86 ever had.
But if a VM can enable things like HSA, and who knows, maybe even quantum computers in the future, that make the same Dalvik apps run on it, then I'm all for it.
