Olympus uses a strange and non-standard 4:3 ratio instead of the 35mm-like 3:2 ratio. Therefore when you're printing 4x6 (most people are), they will have to be cropped at top/bottom a bit. There isn't much four-third lenses out there yet. Yet the camera with that format have ben around for more than a year.
I personally see those Olympus to be a overpriced toy dSLR. Nothing can beat the accuracy of the 'live preview' of an optical viewfinder. You can't do manual focusing properly using electronic view finder (or in this case, live preview).
Also Olympus track record of low-light auto focusing have been spotty in the past. Maybe they have fixed it by now.
