Thought some buyers considering both cameras would welcome this. If you really objectively analyze both camera systems, you'll see that the one argument Leica users have - size and weight - is in fact false.
A Nikon D800 + lens kit can actually weigh LESS than a M240 + lens kit!
I'm getting tired of "professional" reviewers whining and complaining about the "huge & heavy" D800 system. It's actually less heavy if you consider a typical all round walking setup: body + 28mm + 85mm.
I love Leica and used to own an M6. I'd love a reason to buy a 240... but the reasons just aren't there anymore; other than having something to show off as I walk around with my $15K camera system. Not interested!
