Well, I traded a guy on Craigslist my old XP laptop for a iBook G4. I mainly did it so I could get iMovie again. I installed World of Warcraft on it, and that program runs so much better on the mac laptop than my XP box.
One suggestion I would have for Apple, is give up on the browser. The Safari browser BLOWS, and BLOWS big time. I knwo the company I work for has issues on their website with it. My bank Chase has issues. Just give it up Apple. Make Fiorefox the default browser, and invest those resources on another program.
