I know I'm in the minority but I enjoy the 739s and 321s. Sure there are a few less desirable seats, but I like having the new IFE and power in every seat.
I just flew the 739 SAT-ATL way in the back (like 30D maybe?) and I had sufficient legroom. No domestic plane in Y for more than 3 hours is comfortable, so I'll take good entertainment over the extra half an inch of legroom.
