As a new convert to mirrorless cameras (E-PM1) and as someone that never gave cameras much thought, this would have been a great starter article for me. Too late now, but I'm sure there are a lot of people out there that would like to know what is really available.
I've had film SLRs since the late 60s, from manual to auto focus, but never really used them to their full capabilities. When I traveled I always carried my Ricoh P&S film camera, and more recently my FZ35 superzoom (SLR like but smaller).
The E-PM1 was really for my daughter, and she is thrilled. It is full featured, not too big to carry, and expandable. She's had it for 3 days and has taken more pictures than she had over 3 years of P&S. I bought an adapter for the lenses from my 35mm days, but she is still learning how to use the kit lens and the camera, so that'll have to wait.
Time lapse is possible on this camera without anything additional, as is a B setting. And 3D since I have a 3D tv.
