Windows Phone 7 already has a neat way to personalize the start screen with theme colors and pinning various tiles to the screen. Some users would prefer the ability to change the background via a personal wallpaper but I think that option would ruin the clean Metro UI look that Microsoft is going for. What if instead the items on the start screen and various settings would change depending on where you were or time of the day or both? That seems like what the Nokia situations app does and it is something I would like to see on WP7. I would even go further as to wish that it could be baked into the OS, but with the option not to have it on by default. Blogger Manan, had the same thoughts a few months back and I remember seeing the same kind of idea from the Locus OS concept video. What do you guys think?
