Apple has always been a design leader in the computer industry. The iMac and iBook signalled the end of the boring beige box and ushered in the era of cool in computer packaging. And while Mac hardware is undeniably cool, the real greatness of the Mac platform is the operating system. Unlike Windows, Mac OS is a reliable, user-friendly piece of software that does what you want it to do most of the time. But Macs cost too much.
Macs are much less troublesome than typical PCs.
You're still on the hook for the next 3 or 4 years. But there's more software for PCs than Macs. In other words, Mac software as a whole is usually of pretty high quality. We would also note that virtually every major application that runs on PC has either a complementary Mac version, or a similar software package that's file-compatible. The Mac versions of these products often have features that make them actually superior to their Windows counterparts.
