I think there is something biological with people, especially boys from 13-22 or so that leads to territorial extremes. When I was a kid it was Atari/Intellivision/Oddesy 2 between me and my close friends we each had one, so it worked out great. We got to benefit from each other's games. We would go to each other's house and play, depending on which game we wanted to play.
However, we were all Atari Computer people and there was an Atari/Apple war. Atari people would argue theirs is the best, Apple people would do the same. Same sort of fandom as today's rivalries.
It is more fun when you have them all. But if you only have one, you tend to get really attached to it.
