Though a few comments there make no sense and are borne of sour grapes and ignorance. Like:
Uh...huh. Yeah. Okay, I'll remember that next time I'm working in the Unix shell, since it's, you know, a real Unix machine. Or using...
Na. A real unix machine you could hunt down parts from anywhere instead of being hardware locked to one vendor. Even the really weird Sun boxen can usually run stock parts.
That's not sour grapes or ignorance. With a PC, I can run down to Wal-Mart, Radio Shack, Circuit City, or one of the million small computer repair shops and buy a spare HD, CD/DVD drive, etc. From what I understand, Apple retains sole control over their hardware. Am I wrong?
I can buy ANY case I want, ANY compadible motherboard (or hell, any fits inside the case if you're creative), ANY hard drive, ANY optical media reader, and whatever weird attachments I want. Oh yes, and I can put whatever OS I want on it. Lemme know when Apple ships a stock Mac with Linux or Windows straight from the factory. I can buy a PC pre-loaded with any OS on the planet.
I'm not sure how they came up with the slogon "Think differently" when they sell the most restrictive system on the market.
