Photography is my hobby and I've been a fan of the mirrorless micro 4/3 system. I've just purchased a new body, the Olympus OM D M10. Aside from having a pretty good selection of lenses, I like the micro 4/3 system because of the smaller size and weight of the gear. And, image quality certainly meets the needs of most people.
For the average consumer, the question is whether to buy into a camera system with interchangeable lenses or to stay with a single lens camera. For those that don't want to get into multiple lenses, I think a good "superzoom" camera is the way to go. That way, you can have plenty of zoom, but you will have to carry a little bit larger camera than the real small digital cameras that are available. Before getting into the 4/3 DSLR system, and then the micro 4/3 system, I had a Panasonic FZ20 (superzoom) camera, and I captured some really nice shots with that camera, and it was really great having the ability to have such a zoom range without changing lens.
I started a photography club in our community, and the most important point that I emphasize with camera owners is to learn how to get the most out of their camera, i.e. learn how to shoot in different modes (aperture, shutter, manual, etc.) because the auto/priority mode won't always give you the best results. If you take time to understand the relationship between aperture, shutter speed, and ISO setting, you can learn how to take better pictures. And, every camera enthusist should understand the problems created by low light situations or fast action. These two situations are the reason why so many people get frustrated trying to take pics of their children/grandchildren playing sports or other activities where they are in motion.
Also, if you want to learn how to be better with a camera, there's a ton of help available on the internet. I especially like some of the videos available at adobe.com and at adorama.com.
