most of the newer netbooks get 6-8 hours , While my older Dell mini 9, Mini 10 only gets 2 hours,

With 2 batteries you would be able to do most flights

But check the touch pad and see if you like it, and the keyboards are small if you are a good typer ( I am not ! )

Downside of a netbook is no DVD player,

hope this helps a little
