Well, got my M7 today from Chris--he's a standup guy, I gave him a big thumbs-up in the feedback thread. Unfortunately it's pouring and I have an upset stomach, so no snap-happy wanderings today, but wow, what a lovely machine. The film advance feel is not as nice as the M2's, but the .72 MP-style finder is spectacular. The shutter is actually quieter than my M2. And I actually kind of like the exposure compensation method--it's neat how they turned the old dial into something useful, and I'm not getting blinking problems. (It's the old DX reader, not the optical.)
Future upgrades: the leatherette is peeling a bit and I don't really dig the feel, so I will probably replace it someday with vulcanite or griptac. It seems as though the leatherette would be very easy to get off cleanly, is that right? And I would love to replace the advance lever with the MP type--I am aware that it's not swappable, that you need a custom part.
Oh yeah, and I like the black dot! Not as stealthy as Akiva's, but nice.
Thanks for the advice, guys--this is shaping up to be a keeper.
