I've had the M2 a couple of months and the M3 a year or so. The cameras feel indentical to use ... both are a delight with their silky feel and the shutters sound very similar. I find the rangefinder patch a little more distinct on the M2 but the M3's viewfinder seems a little brighter. The M2 just seems like a better camera to me and the frame counter arrangement suits me more!
Oh ...and thanks for the welcome!
