I read that the keyboard is a little finicky. Too small for full time use and it's too big for the pocket. I'm still thinking of getting one personally just for the cool factor as much as anything - an ultra-portable like this is great for going away on holiday etc so you don't have to lug a full size laptop along.

To get the cost down a bit
Maybe 1GB of RAM instead of 2
Don't worry about 802.11n
Internal modem (haven't used one in a long long time...)
Maybe don't worry about the Corsair GT drive

Probably down around half the cost for the upgrades then.
