Personally,

I think the nokia 770 is gonna be ok. (due to its size and so forth) The only worry us 770 owners should think about is if they try to price it close to the 770. Then the question is gonna come up since they are both so close why buy a 770?

Either way, I got to get one of these.

Also, I just put up a forum about the UMPC's with articles and so forth about them. Check it out.
