Yeah, I didn't know what the sizes were. I just picked a number. 19" just doesn't seem far enough away from 21.5", so I went lower. I should've said 17" because I
know those exist (Apple does too).
Those 17" white iMacs were nice, I thought. A good, decent size for regular folks. Imagine one in a thinner, sleeker (and less "chin") aluminum/black enclosure with just a few ports on the back, and going for $899 or so, and still a solid, respectable performer.
I don't think 21.5" (or any number) is necessarily a "sweet-spot". People take to various sizes for all kinds of reasons...what they can afford, their usage habits/patterns, how bulky or small they'd like something in a particular room, etc. A 17" aluminum iMac, even heading into 2011, would sell
plenty. It's crazy (and borderline spec-whoring) to think otherwise.
Some folks, all they've ever known are 15"-17" monitors...they wouldn't know what the hell to do with 21.5" or 27"!
