Microsoft reflects on the failures of Courier, KIN, Courier

Microsoft's had a variety of weird and wonderful consumer devices over the years that haven't gone so well. Jon Friedman, now chief designer of Office 365, has been at the center of Microsoft's notorious product failures, including the SPOT watches from 2004, ultra mobile PCs, the KIN phone, and the unreleased Courier device. At Microsoft's Build developer conference this week, Friedman reflected on his personal career at the software giant and why some of these products weren't successful.The Courier always seemed like a fascinating device to me, even though I wouldn't really know what to do with it.
