I've got the SR 2.2 15.4" MBP and bought as a refurb in April (this year.) Coming from a well-worn workhorse Thinkpad, I've been very happy with it. It does feel a bit 'delicate' compared to the Thinkpad, which I just threw around and beat on the keyboard for a few years. As I've gotten used to the feel of the Macbook pro keyboard, it's gotten better and better for me to use to the point where I just love it. The frequently used keys have gotten smoother and more shiny with use (and I keep my hands squeaky clean, no grease, etc.) which is a bit annoying, but it happened on the Thinkpad too. I type a lot, so there's not much you can really do about it. But, having said that, I actually like the feel of the slightly worn-in keys better than the rougher texture of the brand new ones. I'd prefer if the new keyboards were just completely smooth, so the 'shinyness' wouldn't be so obvious between frequently used keys and lesser used ones.
My only issue so far (keeping my fingers crossed on the GPU) is that the cable from the powersupply seems likely to fail with the way it's designed. The place where the wire comes out of the actual powersupply is already twisted where it had to 'bend' for wrapping the cord up for storage. Or if plugged into a surge protector and the cord is on the top of the unit, which also tends to 'bend' the cord at that spot. Normal use for me has already had me wondering if it was going to eventually short out inside if the wire breaks. I'd like that to be a little more rugged.
But, bottom line so far: it's been impeccable. A great computer, classy design, a huge leap from where I was when considering the overall experience.
So - here's another happy macbook pro customer. It ain't perfect, but it beats whatever comes in second.
