I love(d) the M so much for the IQ and EF compatibility (I have purchased a kit with the adapter). I really like(d) the selection of AF point by touch and I enjoyed the EF-m 18-55 later on holiday, too. I was a huge fan of Canon. BUT: I was waiting more than a year for:
a) a faster zoom - say 18-55/2.8
b) a pancake zoom - say 18-55/3.5-5.6 pancake
c) some dedicated small and lightweight primes - like 35/2 and 50/2
...AND there's no news for such a long time. Not even a roadmap that would make one wait more patiently. So I ditched the M and went into m4/3 world with Olympus OM-D E-M10. Although a bit smaller sensor, I get a lightning fast touch AF, tilt screen, 1.440k viewfinder, a pancake zoom right out-of-the-box and I got the m.zuiko 45mm/1.8 for bokeh shots for €250 (about $330, that is). There is a nice range of lenses (17/1.8 and 25/1.8 are on my list), it's lightweight, beautiful and fun to shoot with. Sorry CANON.
For EOS M users, the EF 50/1.8 mark I is really nice to work with in MF mode...
