i have a pentax Q, the standard prime and the toy wide.
the little Q would currently be my most used camera. it is nothing to throw it in a pocket and head out the door. it also shoots 1080p at 30 frames a second with a total record time somewhere up around 25 mins.
if Pentax get's an external mic port in there somewhere... it would be damn near perfect!
I find that the Q shooting at ISO 400 in B&W is strangely similar to Kodak Tri-X. not bad for $200 including the lens. Plus you know what they say: There is no photograph if there is no camera. (or something like that) The Q fits easily in my front pants pocket.
