I chimed in a while ago saying I liked this idea...
then I actually did it.... then I bought more stuff... my gas never ends!
I traded in my Hasselblad, M3, M6, MM, and a handful of lens for an MP and 50 'lux.
So my remaining was the MP, 50 'lux, VC 21 f4 and VC 35mm f1.4
Couldnt be happier, its small, I dont have a ton of choices to make when I go out and I cleared several shelves of camera gear out of my house (girlfriend very happy about that part).
I did just pre-order an M10 b/c I have no self-control.
That said, anyone thinking about this should do it. I absolutely love the MP, everytime I pick it up it makes me happy. Its just so nice to use, all I ever really wanted was M3 with a meter, welp now I have it. I also really cant over-emphasize the blessing that is a simplified camera kit.
