Who carries around a DSLR with them all the time?

For the past year, I've had a Panasonic GH1 or a Canon Rebel T2i with their respective kit lenses (the GH1/14-140 combo is HEAVY)  in my bag everyday (on the subway, to work, etc)

I finally got sick of it and picked up a black friday special Panasonic LX7

I mainly do cityscapes with it, so slow AF isn't an issue (and I think the LX7 has a faster burst rate than my T2i)

OTOH, I feel like I'm going to "miss" a shot one of these days...
