I've got to agree with Devilstation. Trophies are the reason Home will be successful. I can't imagine many people using the movie thater thing more than a few times (say, to impress their friends one time or something), but I can guarentee you that the Trophies thing will blow Xbox Achievments out of the water. I mean, which is cooler; seeing a list of what you've done, or seeing a room full of these cool 3D tropies that have screenshots and stars and explosions all over them to show what you've done in various games. Add to that the "room" of ALL the trophies that are possible in ALL PS3 games (I can't remember exactly where I saw that pic, but it looked like the reactor shaft of the Death Star with thousands of 3D tropies floating around. Amazing.) THAT is WAY cooler than Achievments will ever HOPE to be.
I suppose the bowling, pool games, and the like will get used often, but I doubt a lot of people will use most of the available features. If you want to watch a movie, just turn on the PS3, hit the left D-pad button once, scroll down to the desired vid, and click "X". It'd be dumb to go through the hassle of opening Home, waiting for everything to load, find a movie theater, wait for THAT to load, and then watch the movie.
Not trying to be a fanboy. Of course, it's hard when you own the best console eve... dang it
