At its annual Surface hardware event in New York, Microsoft announced the expected set of updates to its existing hardware lineup. The biggest surprise, though, was surely the announcement of the company’s dual-screen Surface Neo, which will go on sale before the 2020 holiday season. To make this kind of dual-screen device possible, Microsoft also built a new version of Windows 10: Windows 10X.

Microsoft says it’s announcing the hardware and software today in order to get it into the hands of developers ahead of the launch.
