Out of Milk for a shopping list app. Kindle app for reading (never thought I'd read a book on my phone but spending a lot of time waiting for medical for the wife and I've read 6 or 8 books in the past 6 or 7 months).

Flashlight let's you use the "flash" light to find keys or some such.
Tango to video chat over WiFi or data. Fring, to conferance call (video) with up to 4 people. Ibeer free to carry a little beer with you (fun app). Then there's about 10,000 more depending on your interests, including apps for your banks.
