Not sure how you can think they're the same.
- The iPhone is app centric with a static homescreen.
- WP7 is data centric with a dynamic homescreen.
Different philosophies.

The static homescreen and dull grid system will have to go at some point. People will want to dynamically interact with a living, breathing OS as we go forward IMNSHO.
