Sorry, let me clear up my definition of "pocketable"
Yes nearly all mirrorless cameras won't fit in your typical jean front pocket, but if I can stuff it in my back pocket or my often worn cargo shorts pockets ( with or without the lens attached ) then its will work for me. ( though i'll probably put a clip on it so I can just clip it to my belt or whatever when i'm out.
Mainly I want something I can carry around with me, as I often see things where I wish I had a camera, and my phone just won't cut it. ( for example a car crash today with the car on fire ) ( no one was in the car and police were on the scene but still cool to see )
and just to also clear up I do have a T3i with 5 len's and a battery pack, so basically anything smaller than that will be good for me.
I'm still looking at a nikon s1, as its cheap and has pretty good reviews, I originally was very interested in the M but the more I look at it I don't think its for me ( unless I can find a used one cheap ) as i'm not really looking at a DSLR picture quality level, but just a small portable camera in general. Tomorrow I'm going to go back to the camera shop and talk to a different sales guy and see what he recomends for my needs. If he points me to the same camera as the other guy I feel comfortable with buying it. ( and i'll bring my own SD card so I can take the pictures home to check out the quality on my computer.
