arminw writes "Is it possible some at Microsoft find the iPhone a more attractive platform than the software giant's own Windows Mobile? Engineers in the company's Live Labs have released the company's first application for Apple's popular smartphone--even before making it available on Microsoft's own mobile platform. http://news.cnet.com/8301-13579_3-10122751-37.html Seadragon Mobile, which was added to Apple's App Store on Saturday, is a free image-browsing app that allows users to quickly "deep zoom" images while online and is intended to demonstrate what is possible with a mobile platform. Seadragon is the backbone for Microsoft's Photosynth, which allows users to take a grouping of photographs and stitch them together into a faux 3D environment. So where's the Windows Mobile version of Seadragon? "The iPhone is the most widely distributed phone with a (graphics processing unit)," Alex Daley, group product manager for Microsoft Live Labs, told TechFlash. "Most phones out today don't have accelerated graphics in them. The iPhone does and so it enabled us to do something that has been previously difficult to do.""
