All TOM 738's have the drop down type screens.
If your lucky you'll get to travel on one of the brand new 738's complete with the 'Sky' interior. I was onboard GFDZU yesterday playing about with the new features and it's great. Mood lighting (sunset lighting, night time etc) and flip down TV's above the seats.
Long flight on a 738 but TOM are one of the better 738 operators around imo
