If it's an EeePC, go to wiki.eeeuser.com, and read up on the tips on how to make Windows faster, it really does make a difference. Surprisingly, Windows 7 runs /very/ well on netbooks, and I have to admit, if there's a way to draw me back to Windows, Microsoft needs to get that thing to market.
But yeah, these netbooks aren't speedy, but the 30watts of power they draw when charging an empty battery certainly is easier on the RV's power supply. :)
Curious. Can you pull the battery and operate off of the adapter only? That’s how we run our laptops, here at the house, and the batteries stay good for much longer, too.
