Well, here's the thing: most of you guys are chatting from the USA, meaning that you have a very good connection that allows for digital content download and FullHD streaming.
Me? I'm from Argentina, where Internet speed can't even come close to the ones on USA or Europe. So for us, streaming isn't really the future of gaming, and I much prefer to have a physical copy of my games since, you know, I can lend them to my friends, I can check the games I have without having to turn on the TV and PS3, and they make one hell of a decoration.
