A bit late but still pertinant...I live in an area served almost entirely by commuter airlines using CRJs etc. The airlines encourage people to tag their carry-on bag for drop off and reclaim at the jetbridge/tarmac upon landing. I never do that, since my carry on gym bag fits even into the overhead of a CRJ. It holds my 13 inch MacBook, my prosumer camera, my essential meds and reading matter. Then there is a delay reclaiming when connections may be tight, and, most importantly, there has a been a rash of tagged bag theft in the southern US.
