I have a samsung n110 I use only for diving related stuff but any netbook will do the job although you should get windows xp or windows 7 and not windows 7 starter. i suggest you get one with 3G option or with bluetooth so you can connect to 3g though your phone.
my n110 gives ~7 hours battery life and runs suunto dive planner (similar profiles to my vr3), vplanner, tideplotter etc and gets me internet in most places.
