Well, that's at least a valid reason. Not so sure it's a really great reason, as you could say the same thing about function keys, or two-button mice/trackballs or the like. But it's still a reason.Because it reminds one of a peecee?
I don't have a trackball with a scroll wheel, but my next one will have one. I like being able to scroll, nor would I ever go back to a one-button mouse. Control-clicking is more work than my laziness will allow. I don't necessarily like being reminded of the wintel world, but some things have just become part of the "mac experience" -- at least my mac experience.
