Do you plug in your keyboard?
It's probably a stupid thing to ask but would you plug in your keyboard to the PS3 to play Defiance? I'm one of those people that's not big on using a headset (mine's uncomfortable anyway) and I'm more comfortable initiating a text chat before lending my voice, but that's just me.
It's probably not worth the effort of bringing a keyboard down to your PS3 but I'm just wondering if there's a small population that would rather a quick way of putting in text for region chat, etc.
