My wild card guesses would be Lenovo and Dell (which, out of nowhere, made a pretty solid piece of hardware with the WP7 Venue Pro)

The Venue Pro and the contemporaneous Streak Android models were designed and manufactured for Dell by Qisda.

They were indeed very solid pieces of kit, being aimed at the corporate Latitude-laptop-buying market. My Streak 5 is still going strong after four years.
