Hello everyone, I'm going to purchase a new camera for SO for Christmas. For obvious reasons for anyone who's been on B&H recently, I'm down to either a G3 or an E-PM1. I'm going :43:, as it's the same system I have, and I'd like for her to be able to use my lenses. Right now, her camera is an iPhone; she's not particularly knowledgable about any higher-level camera features. What are the benefits and downsides to each camera, and which one would you choose?
