I agree it isn't a pocket cam, that's for sure (unless maybe cargo pants..would work there). And I'd considered an entry level dslr but if I carry a dslr, I'll carry my good one. If I don't want to carry one, then this gives me great IQ in a small package.
I feel the T2i is a good DSLR that is much easier to carry when compared to a 5d2 assuming I am using a prime or the 18-55 kit lens compared to a 5D2 + 24-105 but yes the NEX is a great small light package that has good if not great IQ.
I don't like that the lenses are so limited. And the menus make me crazy. But otherwise, I'm happy with it.
I had the kit with both lenses and they performed pretty well. I think another lens like a 28-35mm pancake would be a great addition that I would prefer over the zoom that made the camera just to big. The menus where really not bad at all, I found it pretty easy to use. This is what I was really expecting to hate and I found it just fine for this type of camera.
