Not to be a sharp stick in the mud (I usually just ignore new product hype) but is this, perhaps, too much resolution? Should be fine (actually quite nice) if the OS and software can readily scale onscreen content back up to make up for the fact that everything otherwise will get smaller on the already somewhat small 15" screen. Without re-scaling however, the windows, text and buttons and whatnot will be quite small on an already small 15" screen. I'm sure Apple has something in mind other than just chosing a smaller resolution in the display options, because Apple is the bestest in the world at everything and really knows what they are doings.
I was worried when I switched to dual 22" wide-screens for my desktop that their seemingly small 1680x1050 resolutions would not be enough. Far from it, it was the perfect resolution for working. Before that I was used to very large, very heavy, CRT, Sony Trinitron displays. I had 3 of them, one close to a 30", a 21" and a smaller one off to the side, 15" or so. They all had higher resolution than the newer, smaller, flat panels, the largest one went a bit over 1920x1080, don't remember specifically what it was, but once I made the switch I couldn't have been happier. It was much easier on my eyes and I was never craving for more space. After that switch I never much concerned myself with super high resolutions, but I do prefer when possible to match exactly the HD 1920x1080P spec, something my current 12.5" machine doesn't and shouldn't do, but it still has the perfect working space size for imaging on such a small screen.
In all, this just seems like number pushing, which they already were doing before.
