Went for silver bceause it looks like a baby version of my OM2.
I agree that a larger sensor would be nice, but I've come to the conclusion that 4/3 is by now "good enough" for everything I want to do with it. The weathersealing (supposed to be as good as the E-5 which means you can practically stick it underwater), compact size, integrated EVF etc just nails it.
Will still keep my Canon gear, but limited to the things where it really excels. 7D + 500/4 for wildlife, 1DsII + Zeiss Planar and PC-Nikkor and Samyang 14 for landscapes.
