I’m sure you’ve seen the news: Microsoft is delaying the release of Windows 10X---and the dual-screen Surface Neo---until 2021. The knee-jerk reaction is to blame the Coronavirus. But as Mary Jo Foley reports, Windows 10X has serious issues. Including the one I’ve raised since the beginning: Microsoft’s weird preoccupation with dual-screen devices was always a feint to generate more interest in a system it needed to succeed where Windows RT, Windows 10 S Mode, and Windows 10 on ARM had failed. And it always intended---always---to bring its new user experience to traditional single-screen devices. You know. PCs.

This is a big deal.
