And there's your problem. Macs are not designed for techs, they are designed for normal people. You and I have no trouble with 5-button mice and scroll wheels, but not everyone is as comfortable with computers. Macs are designed to be completely usable with one button, while taking advantage of extra buttons if available, which seems like a good decision to me. I do agree that the "professional" Mac models (G4 towers) should ship with a multi-button mouse, but it's a minor quibble.
I would have to disagree. Mac OS X is perfect for "Techs". The power of BSD/UNIX with the ease and speed of Mac. DROOL!!!
