Microsoft CEO Steve Ballmer may concede that the Windows Phone 7 market share is small, but that isn't preventing phone manufacturers from moving to expand it. During a Microsoft Worldwide Partner Conference presentation on Tuesday, Microsoft showed off a series of unreleased and unnamed devices from Acer, ZTE, Fujitsu, and Samsung. The Samsung phone will likely garner the most attention considering how much the thin device looks like the Galaxy S II. Sadly, none the phones gets too much screen time, and there is no word on when the world will be able to get its hands on any of them. Still, it's nice to know that Microsoft and Windows Phone 7 has the support of more companies than just Microsoft.
