I wont own a Sony because I have personal issues against the entire brand, but the NEX5 NEX7 cameras are awesome at photos and video.
The manual controls are easy to use, and the auto settings produce great photos. The only down side to the camera is that it feels like a cell phone that somebody turned into a camera. The sensor is world class tho, and there are adapters to mount old range finder glass onto it.
The panasonic micro four thrids cameras are all great. The GX1 with the pancake zoom lens could be really appealing to you.
You would also be happy with the GF3 if you want more auto features and features in general, and maybe the G3 if a more traditional dslr inspired design fits your hands better.
