This new model would certainly represent one step towards John Siracusa’s goal for Apple to “introduce more, better Retina Macs” in 2014.

This makes sense to me: I'm actually replacing a 2008-era MacBook with a Retina MBP primarily because of the screen and the machine's smaller physical size.

A couple people in my firm are also using older but still functional iMacs, and we'll replace those when the Retina versions hit. Better displays are actually compelling reasons to update (despite what I wrote here: http://jseliger.wordpress.com/2011/07/20/mac-os-10-7-is-out-... a couple years ago).
