Yes Windows 8 was a mess, and the Xbox One's early days were embarrassing, but Microsoft's been sharpening its game with impressive deftness and speed. And now it is once again, hands down, the most exciting company in tech.
Aaaaaaand Windows RT is dead. Microsoft has confirmed that Windows 10 won't be coming to either of the Surfaces that run RT, though an update that offers some of the features will. It's Windows Phone 7 all over again.
Microsoft have been building a software platform called OnSight that's designed to let scientists carry out their work through realistic holograms of the distant planet they're studying. Using HoloLens, of course.
Microsoft has made mistakes. It knows this. But as the company proved today at its Windows 10 launch event, it's also not going to stop pushing user interface design into the future. It's just getting smarter about it.
