Again, you MAC ( using MAC because you MAC people hate it when I say MAC ) people get too worked up over this s***. I have so much fun just irritating you MAC people! it's too easy! canl't a guy have some fun???
MAC!
Jokes aside, Apple sells like 5-6 million machines a year including laptops/desktops. Windows XP alone sells 150+ million OEM licenses per year. That's a pretty big difference. And photo/music people are a nitch group. Our Apple fanboys at my university are slowly moving to PC's now. Apples just don't have the advantage they used to back in the 80's/90's.
It's been a rumor now for a long time, that Apple may very well ditch the computer hardware aspect and go more towards the software/osx/ipod and music instead. They make more money on the ipod now then computers. Will it actually happen? Who knows.
btw, I support both at work. I actually like OSX to a degree. But perhaps some can't see the sign of things to come. We already have Apples...sorry MAC's

ooops I mean Apples running on Intel chips. OSX on intel PC's coming soon. Next is MAC errr Apple clones in the same sense there are PC clones everywhere. that's when the fun begins. Apple has full control over the quality of their machines right now, once they go clone, they lose that. 3rd party companies making drivers for OSX. OSX being way behind windows in that dept. Now, I'm not saying Windows is perfect, far from it, but they have quite a few years of a head start in mass driver support over OSX.
What Apple does over the next 3 years is going to be very interesting.
