For the past few weeks I've been playing with canon's mirrorless eos m.
So far I'm loving it, small enough that its easy to keep with you but powerful enough that I don't feel bad that I don't have the full slr with me.
I also got the adapter so I can use all the same lenses and it does have a hot-shoe for any normal flash.
It also has built in eye-fi support which is nice - I can shoot and have it send photo directly to my iPad.
It's also my first touchscreen camera, ever since I used a iPhone to touch focus and meter I've thought that this is the direction cameras should head.
At the recent sale prices I highly recommend it.
