Well, I'm officially X-less. I just sold my X20 and got an E-PM2 with kit lens for $399 for my "take anywhere" camera.
I know from previous experience with an E-PM1 that I won't be shooting manual with it, but I kept the X20 on aperture priority anyway, so that should be OK. Exposure compensation and such are a bit of a pain on the E-PM...series, at least I think so, but generally they work well as "point and shoot" alternatives, and the 16MP sensor that is the same as that in the E-M5, will make my shooting more consistent. Eventually I hope to get the Panasonic 14-42 PZ pancake for when I need an ultra-compact solution.
