But this is true for the game console market in the comment I originally replied to. When you buy a game you are locked in, you can't put your Halo disk in a playstation or transfer your Nintendo store purchases to Xbox. If you have an Xbox and all your friends load up on Playstation, its going to be a significant cost to get the new console and library you want to play multiplayer with them. For some reason people care more now that its a phone than a game console.
