Jusr a word of warning about choosing a laptop.
Checkout carefully the inbuilt pointer device (mouse replacement)
There are 2 types - a little nipple somewhere around the g/h/b keys, or a flat pad you slide your finger across.
I personally find the pad very difficult to use under "stress" conditions, like on the move in a plane or car, and if your finger is at all damp or sweaty you can get double bounce or double click without wanting it.
The niplle I find esier to control. (and this isn't ment to be in jet blast!)
