That whole website/video is a flat out lie. Last time I checked you dont get WiFi at the beach, in the snow, or on a bridge. The N800 does not accept GSM cards so it cannot do EDGE or 3g. The only way it could do what it shows is if you had it paired with a 3g phone (edge speeds arent fast enough for the video conferencing).

I think that website/video is a great idea of what the N800 should have been able to do, but unfortunately it cannot do that. Why not add the disclaimer in the beginning "Features shown are only possible with a EDGE/3g phone used as a modem when not in range of WiFi." Honestly, thats false advertising.
