It looks like a high-end netbook to me. As long as you aren't looking for extreme performance, I would guess it will probably be ok.
One thing I would like to mention though - if you are going to go the laptop route you will want to get a laptop that has a very good cooling system (I'd also recommend a cooling pad). I have run WoW without too much trouble on an IBM thinkpad t42 and a Dell D600 (much older hardware) but sometimes the game really heats up the graphics chip and if you don't keep that heat down, it will start to dump the load on the CPU and your frame rate will choke. That would be your major worry with just about any laptop not specifically built for gaming.
