WP7 is more like Windows 3.11, isn't it? Everybody knows it, but nobody know why. And it's about to be replaced by something much better.

Yes, I do believe Windows 8 will be a much better OS, even on a phone, than Windows Phone 7. But then, as a Phone OS it will probably be exactly as unfinished as Android on Google Dev Phone and Maemo on N900. And the next version will probably be released four years later.
