I've seen this question floating about and with the recent sales I was able to get a license and put my Macbook Air through its paces in the game.

This is with the Mac Client.

In short, depending on your expectations of a integrated GPU and a fanless notebook, you'll either be impressed or disappointed, but it is viable in a pinch. Although I wouldn't recommend it as your main rig obviously, it's a nice sidekick for travel and crafting/low key activities.
