Windows8Italia has ripped apart Windows 8 Built 7955 and has revealed many new features.
The most interesting is that the Windows 8 app store is written in HTML, but will still be a native app for the OS, which increasingly uses HTML5 as a native programing language.
The app store will also be able to synchronize apps from one machine to another, presumably based on live ID. This will make roaming profiles even more useful.
The OS will also support WIFI Direct, which allows devices to exchange files over WIFI without a router, and also include native support for 3D monitors, cellular networks and componentization (MinWin).
Lastly the OS will also support more 3D UI features as found in Windows Phone 7.
The OS is certainly shaping up to be a massive change from Windows 7, and as Ballmer has mentioned, is clearly the biggest bet the company has made in recent times.
