I presently own a 12" powerbook and love it quite a bit. I was wondering whether anyone here wants a smaller subnotebook from Apple. I certainly do. Actually 4.6 lb of my 12" powerbook is much lighter than even the 5.2 lb of the macbook Ideally I would like to slim down to 3.5 lbs but I guess that's not happening with the heat issues? Wonder how sony gets its small vaios?
