In terms of physical constraints, Ming Thein says that a mirrorless camera is easier to take with you all the time. The Olympus EP1 with a pancake can be in shirt pocket, which means you can take a picture anytime, whereas a DSLR requires a camera bag, a solid back that requires strong will. So physical constraints definitively encourages photographers to take mirrorless cameras, which give the quality of regular SLRs in compact camera format. In terms of the aesthetic differences of larger sensors, he doesn't negate that SLRs will disappear. If you want the maximum quality, and can put the time to prepare, than getting an SLR like Nikon D800E with a great lens makes a lot of sense, with a full-frame aesthetic. Expect though that most of the work produced could be from a smaller Olympus or Fujifilm camera. Cheers,
