The Movie Trailers feature of Apple TV has been a long time favorite of mine. When friends come over we sometimes kill a little time just watching trailers and discussing upcoming movies. Before Apple TV you could also do this via the Apple QuickTime website. There are lots of ways to watch movie trailers, but one thing Apple has done well with this is the user interface and high quality nature of the trailers themselves with many streaming in HD. I always liked the Movie Poster way of seeing which trailers were available as well as doing searches. Apple has now brought this experience to iOS.
iTunes Movie Trailers on your iDevice
As you would expect Apple has done a good job with this App in that it looks very much like the Apple TV experience. You can scroll through the movie posters or do searches. Once you tap on a trailer you can choose to play it or in many cases see still photos in a gallery. Surprisingly the photos can be saved to your camera roll, tweeted or emailed. Beyond looking at trailers and stills the app goes further by giving you a calendar of movies that are about to hit theaters as well as what's already in theaters. You can save favorites of trailers and theaters.
This App just about does it all (almost). I'm not quite ready to give up Flixster just yet. There is no movie rating feature in Apple's App. While you can see Rotten Tomato ratings, you can't rate it yourself and share those ratings with friends. Also there is no way to buy movie tickets from within the App. I would very much like this to be the only App I need, but until Apple adds a couple more features I'll still need to keep at least one of my others. Other than that, iTunes Movie Trailers is a great App and there is no reason not to have it!
