I am doing most of what you all do, additionally:
- use ssh to remote control my house music controller (which happens to be a Mac with iTunes)
- use GPS and eCoach to protocol biking, walking and shopping tours and upload instantly to www.heiaheia.com
- use other GPS software (Maep, Mappero, scanWIFI, GPSlog, etc.
- use FM Radio receiver
- share photos and videos to Ovi Share

and soon I hope to use Carman to read out the internals of my car via the OBD-II bus and Bluetooth...
