I also own an Olympus and have been totally satisfied with it. I've had it for a couple years now and my only current complaint is that even though I can control all settings (apeture, white light, f-stop, etc), it does not have pixel mapping which sucks because I have two stuck pixels.
BUT, my next camera will probably be Cannon's Digital Rebel. My brother has the D10 and I loved it, but I need to set a limit.
