I've always owned a Playstation, and most of the Nintendo's, and although I did buy a 360 (and enjoy it), there's no way I'm going to pay an extra fee to borrow my brother's game. I also don't like being forced to download every game to my machine's hard drive. Blurays can hold up to 50GB of memory (though most current gen games are about 10GB), so how fast will your 500GB hard drive fill up if you have to install every game you own?
Ridiculous.
