why not, mine are:
ESPN ScoreCenter - Free
Facebook - Free
Sleep Cycle - $0.99
Reminders (big surprise to me) - Free
The Weather Channel - Free
Have have others i use quite a bit too, but these are my most 5 useful that i use a lot.
EDIT: I think everyone should also include the price of their apps in case some people are interested in them. I've put mine on there. I realize a lot of people will have free ones, but not all will be.
