I've flown on two NW A320s, a 757, and a 727 DEN-MSP and DEN-DTW over the past few months. The A320 and the 727 were not equipped with an entertainment system; and the 757's system remained dark and silent for the duration of the flight - they didn't even use it for the safety briefing.

United and Air Canada are definitely the winners when it comes to entertainment on short to medium-haul flights.
