If that $800 was including the cost for the 3g access, then maybe I could understand the price. Otherwise, you may as well buy a $250 netbook and one of the USB dongles from Verizon, Sprint, etc.
If it's 800 USD, it'll sell very few units, unless that includes a certain amount of the contract for whatever service you get for the mobile broadband connection.
Looks like Nokia thinks the recession is over or something. An Atom inside? I'd pay USD 300, contract free, and they should thank me for that. If not, I'll find a REAL notebook for that money.
