Yesterday Microsoft actually demonstrated Windows 8 for the first time at the D9 Conference. The breakdown of what was showed is as follows.
• Fast launching of apps from a tile-based Start screen, which replaces the Windows Start menu with a customizable, scalable full-screen view of apps.

• Live tiles with notifications, showing always up-to-date information from your apps.

•Fluid, natural switching between running apps.

•Convenient ability to snap and resize an app to the side of the screen, so you can really multitask using the capabilities of Windows.

•Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.

•Fully touch-optimized browsing, with all the power of hardware-accelerated Internet Explorer 10.

Microsoft also showed the ease of movement between existing Windows programs and new Windows 8 apps. They are also optimizing the new user interface for touch, it works equally well with a mouse and keyboard. With people getting into the touch screen more and more and the affordability of the touch screens coming I wouldn’t be surprised that Windows 8 will come mainly with all-in-one PC’s or with touch screens if you prefer a tower. Below is a Windows 8 Preview of sorts, enjoy!
