Some macs dont run OS X. Like mine. The one I have invested so much cash on. I fear that I'll get left behind. I guess I could upgrade to a G3 or G4 somehow but I've heard mixed stuff about doing that. But I've got a new PC that I'm slowly useing more. There are so many little programs that dont work on a mac. But I actually like them both. If I had a playstion 2 and wanted another game system I wouldn't just buy another one- I'd get an X-box or at least something else. If it works why fix it? I find I just end up breaking it then.
