I can't recommend the OM-D and EP-5 Olympus m4/3 enough. I know the OP has already made a decision and bought the goods (very nice camera, by the way), so this is more for anyone reading this in the future..

The in built image stabilisation is good enough that I can, with some breathing control, hand hold a shot at 1/5 of a second. 1/5! Hand held! (17mm).

IQ is as good as, if not better than my Canon 7D, and it is a small and light system. the only downside is that batteries only last 300 or 400 shots. (I am used to over 1200 shots with my 7D), but no drama - the battery packs are small.

The buttons can be customised, and there are individual dials for aperture and shutter speed (for those of us with some idea as to how to shoot), and the auto modes are plenty good enough for those that are not so confident with manual settings.
