I'm still amazed they ended up with 0% market share in mobile phones. That took a some effort, considering they had Windows CE and Windows Mobile for years. Then Windows Phone, and they kept changing the APIs with every release so that nothing was ever backwards compatible. In a CMD shell I still have to use the goddamned backslash because of slavish compatibility with CP/M from 1974, but on the phone they create an incompatible set of APIs with every release. Congratulations, guys, well done.
