I'm watching this thread and stealing suggestions for a netbook purchase.
I'm actually in the market for one for my wife. She has a GW laptop that won't stop overheating. I've taken it apart, all fans work, and the copper heatsink has been thoroughly cleaned and had silver paste reapplied. It is a matter of time before it goes tits-up. I've already copied everything to network storage, and will likely just set her up to work from that with her new system, which makes a netbook more applicable.
One additional request above and beyond iMav's list, none of the glossy screened crap. Who can see the monitor through all that glare??
