Years ago, I had the opportunity to field demo a Windows phone for a cell phone company. It was an interesting demo, as Windows phones only run their own apps. While the phone itself worked just fine, the lack of apps was killer. Jump forward about 5 years and Microsoft has apparently decided to pull the plug on the Windows Phone adventure. One of the biggest issue I saw with it then and now, is that there is no easy way to create apps for a Windows phone.
So farewell to the Windows Phone. Looks like Android and Apple will just have to slug it out amongst themselves.
