I've used Windows at home and Macs at work for years. I've always wanted to ditch Windows. But I've never seen Macs as a better option because of the expense and the fact that you're tied to proprietary hardware as well as software. Linux on a PC is in my opinion the best option because it works on any computer, so you're not tied to Apple or Microsoft for anything. And therefore it's cheap. I understand the appeal of Mac elegance if cost is not a issue. But the basic Ubuntu desktop is plenty elegant enough for me.
I don't want to get into the old OS wars... But just pointing out the other option.
