1. No instant messenging.
2. No tethering using it as a modem for your laptop on the go.
3. Slow, like really way slow compared to sprint.
4. No terminal, no ssh
5. No streaming radio. I have no interest in having lots of space for mp3s. I don't even have them on my lappy barely because I like the surprise of internet radio and have become accustomed to it.
6. No bluetooth means no GPS, no wireless syncing.
7. No way the battery could outlast the double battery I have on my phone right now and the battery is not easily accessible for switching.
8. No flash or java.
9. No third party apps.
10. There doesn't appear to be a file browse for uploading pictures from your phone to a website. LAME!
Look I found this later on macrumors. The battery is soldered on so you really can't switch it easily.

Nevermind I figured it out.
Is it possible to post to (e:strip) via email?
I like it so far. It's really nice and the keyboard work pretty well.
However, the interface is really nice looking especially compared to windows mobile.
thanks Paul! I needed a reason not to covet the iPhone.
