I cannot imagine that I ever lived without my iPhone... It feels great to be connected to the internet 24/7. The apps make it even better. These are my favs:

1. Things
2. Recorder
3. Picoli
4. Exposure
5. Remote
6. Google
7. Twitterific
8. VisuaRadio
9. Send Contact
10. Converter

Next to these apps lots of websites have their own iphone version (Amazon, Vox, NYtimes).
