some of the things I really like:

- tv out. Great for letting the kids watch their movies while away from home.
- Skype over wifi. I have a pay as you go plan through TMobile. This allows me to make the majority of my calls without using any minutes. Result: I pay less than $10/month for wireless services. And as a bonus, the pay as you go plan allows me to use m.yahoo.com for free which gets me access to my email as well as news, etc. (yes, I'm a serious cheapskate)
- easy upload of pictures to my Flicker account. I don't even bring another camera with me anymore.
- FM transmitter. Super useful when driving a rental car.
- outlook calendar sync through PC-Suite. My company does not have an external exchange server to sync with but using PC-Suite I can sync my calendar and contacts which is all I really need.
