That could probably be true, for both Nokia and Microsoft and all the people working for them.
I just don't see the current Nokia (smart)phone users switch to Windows Phone based devices. I also don't see the current Microsoft Windows users switch to Metro UI on Windows 8.
I just don't see the advantage.
Maybe I'll get it when the new Windows 8/phone/RT stuff is out. But if customers don't switch, the problems for these two companies are only just starting.
