I'm wondering.. Chinese have built all sorts of things we never knew we need in our lives. I'm wondering, is there anywhere a physical smartphone keyboard I could purchase? The old-school numpad, like on nokia 3310 or so.

I sometimes find myself in situations where I'd like to type the whole message w/o looking at the screen. Touch-keyboards make this an impossible goal. Having an old-school physical kbd would be perfect for the job!
