I'm working from home this morning and have a lot to do, so pics will have to wait until later today---but I'm taking a coffee break and decided to write up a little bit more detailed review than yesterday.
The machine is awesome. For current owners of 17" C2D MBP models, the upgrade is incremental (obviously, from the specs), but the new high-res screen alone is nearly worth the price of admission, if that sort of thing is important to you.
The higher resolution and resulting smaller UI elements took me about an hour to get used to, after which I find that I really prefer the high-res. Going back to my 20" iMac and 15" MBP, suddenly the UI on those machines looked a little too big and a little less refined somehow. Pixel density is the thing, because even though the fonts & icons are noticeably smaller (but seem to get bigger as you acclimate), everything is very crisp.
The screen is bright! I'm not certain about comparison with the last 17" MBP because I no longer have that one for a side-by-side comparison, but I'm going to go out on a limb and wager that the new screen is somewhat brighter than the last one. (Note that the screen on the new 1680x1050 model has exactly the same mmod in profiles as the previous one; it's the exact same make/model of screen as before. The new high-res screen is designated 9C69, for anyone wanting to research its manufacturer and tech specs.)
I'll agree with a previous post in saying that the backlighting isn't quite as uniform as on the new 15" LED displays, but I would also say that it's definitely more uniformly lit than the old 17" display. It's really a gorgeous screen. Aside from being non-LED, I would say it's probably the nicest screen Apple has ever sold. Although I had been hoping for 17" LED screens with this update, I don't think I'll have any non-environmentally-related regrets about going ahead with the purchase. I'm really, REALLY impressed with this display.
Operating temperatures seem no higher than on the last-gen 17" MBP, maybe slightly cooler but time will tell. Noise levels are about the same as the last one, too. My particular unit vibrates at a frequency that sets up a resonance on my work desk at home, but then so do most of my electronics on that particular desk. On all other surfaces at my house, no problems there.
If I wanted to really nitpick, I guess the only "flaw" I can find so far is that the lid is about 0.5mm higher on the left than the right when closed. Since 5 of the 6 MBPs I've owned, along with most of the others I've seen, show the same ever-so-slight difference, this is the one "problem" that my overly neurotic a** can live with.
I haven't really done anything intensive enough to show off the differences in the new GPU. I did notice that the grey boot-up screen now scans down instead of just popping up instantaneously, so I'm betting that the new monitor has a slower response time.
Viewing angles seem slightly improved over the last rev.
Umm, I can't think of anything else. I'll try to get pics up later. Any questions?
