This doesn't work. I have seen this being pitched repeatedly just to have it run headfirst into a concrete wall. X86 is (still) not mobile friendly, and XP is downright mobile suicide in all aspects, power, ui usability, size, battery life, etc. As I said, every year somebody tries to do what you say and fails miserably. Last year's attempt was the xpphone, the 2010 fail is still lurking, but I'm confident that some will take the fail-trophy this year, too..
