Sierra, a longtime wireless modem maker, has shifted gears and annouced a Microsoft powered smart phone. It's called the Voq Professional and lacks many of the accoutrements that most other phones with the "smart" label take for granted, namely a camera.
It does have a neat flip out QWERTY keyboard and support for Microsoft Exchange, so it should appeal to the business user. Although, it seems to run on the large side, which is a big no-no for mobile professionals.
