every platform is also a community. a network of players, like a neighborhood, or a bar. Your friends & acquaintances are there. The whole is more than the sum of it's parts. It's more than just hardware, or exclusives.
I switched from PS to Xbox a few years ago, because my family and friends were playing there.
There's also some nice technical benefits, but compared to my friends, who cares?
It'd be nice if companies were forced to allow interoperability, at least optionally, and had good standards for making that easier on developers no matter what platform or title. There are some valid reasons to segregate PC and console gamers (depending on the game), but that kind of social network lock-in is mainly an artificial constraint which is anti-competitive and ultimately anti-consumer. Those are the kinds of barriers the internet should be removing from our lives.
