More stuff on the to-do list:

1. Mobile media with Orb (see what I did with Orb on my Nokia 770)
2. Voice over IP with GizmoProject (related post)
3. GPS with Google Earth. (Assuming I can get bluetooth dial-up networking to work)
4. Wardriving! (must check wifi chipset and compatibility)
   
5. User suggestions! (post what you want me to try in a comment.)
