Microsoft must be reading my mind. I have been moaning EVERY time I need to title a saved game image or type a message to a fellow gamer. I did use a USB keyboard for a bit, but it's too awkward and takes too much space.
This messenger kit keyboard is a work of art. I just held it in my hand for the first half hour marveling at the design. Once it's fitted to the 360 controller it's even better. It fits so well that you would believe it's always been there.
It is so easy to use, does not get in the way and it always there when you need it. No more excuses for leaving the default ambiguous names for files.
I would buy another, but that would be just silly :)
