I agree. I usually do my EC tunnel buying/selling on my netbook while working on my desktop PC (VNC-ing into work won't allow me to connect to EQ Emu servers). It's also useful to do those 6 minute, 1 spawn camps scattered around the continents.
On long road trips I've also tethered my blackberry to my netbook and played that way. Never once suffered a dropped connection, which I can't say about my cable internet at home.
Edit: I use this model and I don't need to turn off/tune down any video options. The screen size is the real limiting factor.
