Why do poeple hate Xbox 360's

why do so many poeple hate xbox's and xbox 360's so much all the games I played on xbox have been very good, and the grafixs are much better than alot of games on the ps2 and game cube.

A lot of people claim it would have been a completely different game, like an RTS-FPS hybrid, just based on the Macworld video.  I've seen no evidence that the game would have been different though.
