Unfortunately, I have many, many flights on this beast. I strongly prefer row 1 (1D being the best seat, IMO) to the exit row because the legroom is as good or better and the seats are slightly more comfortable. The padding on the exit row seats is almost nonexistent and is one of the least comfortable seats on any US plane. Overhead room is very limited such that even bags which fit under the seat on mainline aircraft often won't fit. I think the dimensions are about 16" deep and 8" high. Rollaboards are totally out of the question and you get to line up on the jetway to wait for plane side delivery with what seems like the entire plane.
