I have been using Mac's for years. I cannot agree with the comment that apple abandon their products. The switch to Intel caused a fuss, but most new applications are Universal Binaries that work on both PPC and Intel. Not only that the vast bulk of Mac based software is PPC based. Even if I am wrong about Apple, the developer base supports legacy systems for many years.
I am not an Apple nut like a lot of Mac users, but I find my macs to be increibly stable and relaible. I really cannot remeber the last time my system froze or crashed, not only that it is so easy to use peripherals with macs, the whole driver thing is hardly ever a problem.
