I think the picture shows it all...the Mac has crashed and is stuck on its startup sequence. Maybe I had a bad experience with Macs, but I got that kind of behavior quite frequently, probably because I got so frustrated with it and broke it somehow. Not that Windows is any better though; I don't like Microsoft, I use Mozilla Firefox because I can't stand IE. It's just that Windows XP supports the most games and applications out there and if you don't use it, you're limiting yourself to the applications and games you can use. The truth is computers are complex things and with so many things able to go wrong, something will eventually go wrong. I haven't used Linux but aparently it's quite stable compared to the commercial alternatives.
