Um, no?
Seeing the Surface tablet announcement, I just finally understood why everything was being Metro'd. Metro on a desktop PC is stupid and MS knows it, but they weren't Metrofying desktop Windows because it was for the desktop. MS wants Windows on desktops, laptops, tablets, and phones. ARM had finally reached the point where it was powerful enough to run Windows, so MS just said fuck it, let's put Windows on ARM and call it a day. Obviously, in a world where all Windows devices now run real Windows, Windows Phone is completely unnecessary and superfluous, therefore it is now dead.
I'm expecting on Wednesday MS will announce Windows Phone 8, which is actually Windows RT for phones.
