I have to say that I disagree with the OP and agree with most of the other people. Generally speaking the front of the plane gets off before the back.

Assuming that the plane is all one class (y) and I'm in seat 1A, the OP seems to be saying that, just because the people in the isle seats can get up first that I have to wait for ALL of them to deplane before I do? Seriously, there's no way that 1A should have to wait for the guy in say 45C to get off before they can grab their bag and go.

I'd say front before back, unless you're elderly, invalid, have very large/awkward bags or other reasons where you would significantly hold up those behind you, in which case they should wait for a significant gap in the line. Even that, though, would just be a courtesy.
