Well, after spending some time with the N800, I can't be anything but dissapointed.

Battery life: bad. The battery sometimes discharges itself when the device is supposed to be off.

Streaming audio/video: not working 99% of the time

Videoconferencing: not working

Videoplayback: 99% 'no codec' error

Browser crashes randomly 3-4 times per hour

This device isn't finished and the new firmware doesn't solve any of these problems.
If you're stil in doubt of buying a N800: don't. You can do better things with your money. I am sorry I bought mine.
