I used to spend on average 2 painful weekends a year recovering from Windows system crashes and malware infestations. I accumulated notebooks full of arcane error messages and notes on convoluted 48-step installations...ugh, the horror!
After a nightmarish 4th of July weekend wasted on trying to recover my Wintel machine that was rapidly becoming a doorstop -- and having just received a pay increase -- I sprung for an iMac. It had several annoyances, too: I'm still not used to some of the Mac behaviors, the shortcut key combinations seem awkward, the difficulty of finding an Apple-ready ergonomic keyboard seems idiotic, and the one-button mouse...don't get me started.
BUT -- since then I've had ZERO system crashes, and also have been spared the several-times-a-day minor crap-outs and reboots that Windows users just live with. It has made a huge difference in my peace of mind to have a reliable system. (But, yes, I do make frequent backups -- no computer system is permanent or fool-proof.) So the extra up-front cost of an Apple system is more than offset by the efficiency and reliability, when compared to a Micro$oft system.
AND I have really enjoyed the speed and processing power of the Mac (I've upgraded to a Mac Pro with SSD main drive) and the excellent software offerings (Logic, Soundtrack Pro, Bento, etc.)
Am I a fanboy? Do I wear turtlenecks and say the Mac is "insanely great"? Do I consider myself superior to Windows users?
Nope. If a Windows system (or Linux, or whatever) offered the efficiency, scalability, versatility, and reliability of the Mac, I would be using that. It's just a computer -- let's not get too emotional about it. It sure is a great tool, though.
