Electricity is so expensive in Southern California that I think I would like to switch from my ginormously honkin' desktop to a laptoppy thing. This would not only use less power in general, I could more easily shut it down/place it in sleep mode when I'm not in the house or when I'm sleeping. I would also like it to be relatively portable, so none of that "portable desktop" with 30 minutes of battery when not at an AC outlet bullshit. I would like for it to be able to run WoW reasonably well, but am not really too worried about other forthcoming games.
1) I kind of want an Intel-based Mac, but I have no idea what kind I should get.
2) Is that stupid? Should I get some sort of PC instead?
Thank you for your advices!
