To be honest, when Micro Four Thirds format was announced, I couldn't really see the point. Sure, the cameras were slightly smaller but not by much. If you look at older Micro Four Thirds cameras like the Panasonic G1 and GH1, they're smaller than something like a Canon Rebel but not by a serious amount. You still can't fit them comfortably inside a jacket pocket and you're missing some comforts we are used to on a traditional DSLR, not to mention the fact that introducing a whole new camera system means people have to purchase a whole new set of lenses. However, the most recent batch of m-4/3rds bodies have been sleeker, more attractive and more fully featured in comparison, showing that the format is evolving into something that is if not a competitor to the old guards of Canon and Nikon, then definitely a niche alternative with a legitimate market share.
