GameFAQs poll of "platform with most minutes played over last month":

It actually goes in line with what that Sony exec is saying, if you can believe that.
I bought a PS4 and it was for an exclusive game.
Reasons for buying a PS4:
-Exclusive games
-The biggest software selection for any current gen console
-The most powerful console
-My friends play mostly PS4 and I want to play with them
Are there other reasons to buy a PS4? I could throw a poll together but what would be in it besides those 4?
PC will always have the biggest software selection, because it's PC.
I could see getting Xbox if most of your friends have Xbox, because most of the factors are pretty similar. Xbox is not that far behind on exclusives, software selection and power.
