Because PPC Rulez d00dz!! Just kidding. Seriously though. Mac users are used to certain things. Like buying a Mac and having it supported for a MUCH longer time than a PC. The reason lots of Mac users can "get by" on a 1999 B&W is because the Mac upgrade cycle allows that. Even when you buy a new Mac, you keep or donate your "old" one, because you KNOW it's still valuable. How many people keep PC's that long? Mac users will lay down cash for a Mac Mini which is beneath any mainstream PC spec wise. This works in Apple's favor too. The Apple engineers put lots of time and effort into producing machines that smoke beige PC boxes on many other levels besides raw processing power. Now with Intel chips having a new update every 30 days your shiny new Macintel will seem much more outdated much more quickly. Apple will feel pressured into introducing new models faster to compete with other Intel based products. In turn, developers will jump to take advantage of the "latest and greatest" making new apps that won't fully function if even run at all on your new box. Also in turn, with the time between shiny new upgraded Macintels shorter than the current PPC based Macs, the Apple engineers will be pressured and start to slip. Further down the road the Macintels will LOOK AND FEEL more and more like regular PC's - - - and what is Mac, if not LOOK AND FEEL? Sure that's not all, but it's a big part of the Mac experience. You want Intel in your Mac, that's fine. But you also get the headaches of a much faster development cycle such as buggy software, less design, more exploits, less resale value, and the list goes on. Come January, I may be in the market for another Mac - but mine will likely sport a G5.
