The Philips PT903/37 is a standout among standard digital portable TVs. Though it lacks support for Mobile DTV, those signals can't be found outside of some of the larger TV markets. On the other hand, performance with regular digital TV signals is much better than average judging from user feedback. One reason might be the detachable antenna, which can be placed where the reception is best independently of the TV. The 9-inch screen is larger than most portable TVs, which can be a plus for use, say, on a kitchen counter -- as well as a minus because it makes the TV harder to lug around. Many appreciate the inclusion of an FM tuner. Reports say that the Philips TV doesn't play well with a cable box, but it does include a clear QAM tuner so that it can display unscrambled digital cable signals. Some grouse about the nonremovable batteries and the relatively short run times between charges (around 3 hours).
If you are interested in a portable TV that receives Mobile DTV signals, the RCA DMT336R (*Est. $160) is your best bet. Reviews indicate that it, too, is an above average performer with standard digital TV signals, and that reception with Mobile DTV signals is solid, even in a moving car -- something that's not really possible with a standard portable digital TV. High cost and a small screen size (3.5 inches) are the DMT336R's biggest negatives, and it can be hard to find.
