One of my favorite windows phone 7 apps is shuffle by album. I used to use the authors software and have followed his blog ever since. Like it so well it's pinned to my menu.

I also like the weather channel app - best part is that it shows current conditions on the title.

Just downloaded and set up remember the milk. The app is called WinMilk - sure wish the outlook task was supported in the office apps but oddly enough it isn't.
