Got my first taste of the MD80 seats last night -- felt a little less roomy than the 757s but I was much more happy with it. The seat itself was very comfortable, and the tray table is more functional (can lean back and turn it up with my laptop, and turn it out to the side if I want to get out).

As a side note, service was very professional and attentive. Maybe I'm just not used to it, but I see how y'all get addicted...
