Walter S. Mossberg on Windows Phone 7 "I've been testing two of these initial Windows Phone 7 phones, the Samsung Focus from AT&T and the HTC HD7 from T-Mobile. My conclusion is that Microsoft has used its years in the smartphone wilderness to come up with a user interface that is novel and attractive, that stands out from the Apple and Google approaches, and that works pretty well.
But I couldn't find a killer innovation that would be likely to make iPhone or Android users envious, except possibly for dedicated Xbox users. Even built-in Office can be replicated with 3rd-party Office-compatible apps on competing platforms; and iPhone and Android phones also can interoperate with Microsoft's corporate Exchange email, calendar and contact system. So for now, I see WP7 as mostly getting Microsoft into the game, and replacing the stale, complicated Windows Mobile system that preceded it. It'll get better. The company is already working on a copy and paste system, and said it's coming early next year. But, today, I see WinP7 as inferior to iPhone and Android for most average users. It's simply not fully baked yet."
