I remember someone doing a list like this back when 3.0 came out. Hadn't seen it yet so I thought I'd start it this go around. There are apparently 100 new user features, let's try to list as many as possible. Here we go. 1. change wallpaper 2. Unified inboxes 3. Spell check 4. 5x zoom in camera 5. Tap to focus in video camera 6. Multitasking 7. Folders 8. Zoom text for messages, mail, etc. 9. New dock (not really a user feature but I like it ) 10. Birthdays in calendar app 11. Rotate camera roll photos 12. Photos organized by albums, faces, events and places 13. Character count for SMS 14. iBooks 15. Control location services for each app 16. Spotlight search will give Safari or Wikipedia as an option 17. Passcode lock can now be a word or numbers 18. Create playlist in iTunes app 19. Game center app (not functioning right now) That's all that I've come up with so far. What else have you guys found out there?
