Yes, I've already ordered mine. Cool features include:
- EVDO Wireless Internet Access - Anywhere, always on, for FREE! No service contracts, no worries!
- Free Wikipedia access - The power of the world's shared brain anywhere on a great screen
- E-ink display - no backlight need apply, no eye strain, it looks like printed paper
- Wireless purchase books where ever you are
- 3 thousand launch titles in Sci-Fi/Fantasy alone (88k total)
- Email content to your kindle wirelessly
- Just In: You can go to arbitrary web pages! (according to the device manual)
There are some disappointments. I don't think a $400 device is going to really revolutionize things, but I hope it will get cheaper as time. Also, its not shipping with PDF support. Hopefully that will change, but it does support MOBI files, which I hear there are PDF -> MOBI file converters.
Anyway, I'll be getting the device tomorrow, so more on it then! Welcome to the future!
