Have you played world of warcraft or any games on these laptops?

Netbooks are not meant for playing games. If you want to play WoW, you can get any low end/priced (~$400) laptop - most new ones come with at least 2GB RAM and 2.0GHz dual core processor. If you want to play newer games on a laptop, you should expect to spend at least $800, but more likely ~$1200.
