if macs are properly cared for they will hardly ever break down or require repair - the mac operating system is much more stable and macs hardly ever get viruses - they are the best computers for graphics exceleration and they are much smarter than pcs - they are much faster, have better memory, hard drive, etc - because of the way their processor works comparitively to a pc they last a hell of a lot longer-
down sides to a mac (other than a g3-g5 tower) are - they are harder to find gaming software for (which who needs with xbox, ps2, and game cube), they are harder to upgrade (if you have an imac or toaster/cube), and the earlier imacs and other g3's had some overheating issues - but i have a 333 G3 and it is comparitive to a 650 pc so it's all good

(and do i even have to mention imovie, studio monitors, mac flat screens, firewire, ipods, etc -- apple is the best - yay steve jobs!!!)
