I don't shoot m4/3 because of size

This is pretty much me, except I'm coming down from a full frame Canon kit.  I will grant that for my style of shooting (landscape, portrait, product, street) the autofocus is better in some circumstances.  With regards to image quality, it's not that the cameras are technically better, but they are more than good enough for my needs.
