Same here! I just picked up a EOS-M in black (black has a different, better finish than the other three colors) with the kit zoom lens for 389€. The pancake EF-M 22mm f/2.0 and a couple of extra 875mAh Li-ion batteries are on the way from Hong Kong.
What I like is the extremely small size, the build quality of both body and lens, the shutter sound, responsive touch screen and some of the software features, such as face recognition, object tracking and "night shot without tripod". This is also one of the few mirrorless APS-C compacts with an external microphone jack (good for those wireless mics I still have).
After the 2.0.2 firmware update I think the AF speed is just fine for most situations. The cam has an AF assist lamp as well and if you hold it with thumb and index on both sides you probably wont be mistaken for a pro or terrorist. The small flash unit that comes with the kit is also a wireless master for other off-camera canon flashes. I'll be getting FD and Leica M-mount adapters initially followed by Contax-G and Nikon at a later point.
Probably when the price gets low enough and more EF-M lenses are introduced this will become a bit more successful than it has been so far.
