The Microsoft Courier. The canceled legendary dual-screen computer from 2010 made a brief appearance during a session at Build 2018 today. In the session, Jon Friedman, a designer who worked on the courier, talked a little bit about what Courier was and why Microsoft decided to cancel the product.

The story isn't one we didn't already know, but it's nice to have a more official account on the matter. In short, the reason it was canceled is because it didn't fit in with what Microsoft were doing in the Windows space at the time. Courier ran a custom version of Windows, but at the time Microsoft was focused on making Windows 8 and Windows Phone 8 the flagship versions of Windows for all devices.
