I've owned SLR's and DSLR's since the 1970's, and there is still something foreign to me about holding a camera away from me and staring at an LCD screeen to take a photo. I've also had a number of "second" cameras, that are smaller, and easier to take on a trip, etc. -- most of them have been the Canon G series (currently a G11), with their obvious OVF flaws, but at least they had OVF's. I got excited about the X30 and bought one and love it. It's a wonderful little camera, the EVF is fantastic, image quality is excellent, and all of the controls and specs I would want are present in this camera. A smaller body would have been too small for my large hands, and a larger body would have been too big to fit into a coat pocket.
Ibida Bab: I would ad a larger sensor, fold-out lcd, AAs and we are near perfect. I wondering towards a Pentax or a Sony this Fall.
Spot on HowaboutRAW. The G15 isn't meant to compete with the G1X.
