I really loathe not being able to type info into my XB1 via a chatpad, like the one we have for the 360s, and I have not heard anything about the possibility of one for this system...Is this even in the plans for the XB1?
A friend of mine has a third-party chat pad that plugs into the controller like the 360 version and it works just fine he says. There likely will never be any version produced by Microsoft as the SmartGlass app seems to be the replacement and it is what
I use on my phone and iPad for all typing. But you never know, Microsoft has done a good job of listening to its users since launch and many surprising things of happened.
There are 3rd party ones that you can find on amazon and the like. They are nothing more than USB keyboards. They require a USB fob to be plugged into the console. Also looking at them they block your headset ports.
