Except, of course, that the vast majority of Windows apps have to be rewritten for the Metro UI first. And then—if there’s any lesson anyone should take away from iOS, it’s this—you have to understand that the user experience, no matter how similar both the developer API and the user interfaces are, is different on the tablet, the phone, and the desktop. There’s a reason that iPad users don’t run iPhone apps on their pads unless there’s no other choice, and that iPhone apps don’t look like iPad apps but just smaller. Microsoft appears to be preaching the write once, run anywhere gospel of virtual machines through time immemorial, and it’s quite possible that they’ve got the virtual machine problem finally solved. That doesn’t mean they have the user experience problem solved.
With that in mind, I present my boldly flavored bowl of claim chowder.
