Microsoft shared Windows 8 at Mobile World Congress in Barcelona today.
"The first thing you're going to see with Windows 8 is that it's beautiful, it's modern, it's fast, and it's fluid," Windows head Steven Sinofsky told the gathered crowd.
Designed with the new Metro interface, Windows 8 is a mix between an app and an operating system.
Sinofsky seemed to have a stab at Apple and Android with their world of apps during the presentation.
The Verge reported him as saying: "There's too many hard stops between phones and desktops and tablets. Apps are part of those either, or scenarios. You use this app or that app. That's not the right way, these islands of apps. You should add one app, all the other apps get better."
Windows 8 includes a slide lock feature familiar to Apple users, lays apps across the desktop much like the newest Windows smart phones. Internet explorer allows you to navigate between pages by swiping left to right and back again.
