For you guys that have the 75, take a look at the 55 if you can. See if you don't see what I'm talking about. Small size means it gets dropped a lot. Menus and onscreen displays are non-intuitive. Excelent DVD player.
Portability is a bonus.
Picture quality is excellent. The build quality is great. Will work nicely for a second dvd player too. This battery DOES last four hours, I can usually watch two movies on the plane with this unit. Battery really lasts 4 hours.
