These internal Microsoft videos, provided to Wired by a person who worked on the project, show focus groups testing the ill-fated Kin. According to our source, these are pre-production models that changed very little from the shipping product, although “performance improved some prior to shipping.” Watch them, and you can readily see why the project tanked: Kin phones just weren’t usable. Or, as our source described them, they were a “pile of shit.”

Why should we believe that the latest round of Microsoft products are any better?
