Thanks for your input everyone. It looks like it will probably be the M7 for me, at least for now! I go everywhere by foot/bike/public transportation both at home and when I travel, so weight and portability is the biggest factor, and it looks like it wins hands down. I do like the range of lenses and close up focusing of the Pentax, but it's not critical to my shooting, and I have other systems that can do that anyway.

Only slightly lighter, but I've heard people say the ergonomics are much improved.
