To add:
PhoneAlarm: automates switching of profiles and has neat home screen plugin (
here's my homescreen)
Facade: Show multiple calendar entries on home screen (as opposed to only one)
Styletap: Run Bike or Die on your Q
I guess it's good for other Palm apps like Kinoma
Newsbreak: For RSS, homescreen plugin available
Sling, Resco Exp,Tube for subway maps, Sprite Backup for backups, Mortscript for Scripting, Java for gmaps & gmail & other etcs
Ae Buttons Plus: Still a great task switcher!
