Are you remembering Windows Mobile? That sucked, but Windows Phone did not (and was famously built by a totally different team). But it was too little, too late.

This seems to show another of MS's big problems in those days: too many different products doing the same thing, and a lack of focus. IIRC, they went from Windows Mobile to Windows Phone (version x) and then to Windows Phone (version y, totally incompatible with version x). Each time, this alienated 3rd-party developers because all the apps they wrote wouldn't work on the all-new platform.
