Because you listen to music that has nothing to offer doesn't mean you should knock bands that try to take the simple act of listening just a little bit farther. I have tried this and he's right about the flow. the album also plays well the original way. The fact is, stuff like this is fun. it has nothing to do with pretentiousness, it's about delivering a message that requires a little effort on the part of the listener. You don't have to like it...or more likely, get it; but don't make pointless statements about the material to make yourself feel better or others feel worse about something we enjoy and you do not. Lateralus is a concept album and therefore it tells one story from beginning to end. The msg of each song doesn't change just because you change the order of the tracks. But the flow of the story and the music, without the lyrics, is different, and depending on your personal views...better. If you don't like tool or you're a closed minded bastard, then this forum doesn't apply to you and you should go away. The end.
Tool is this generation's Pink Floyd.
