For the past few weeks, developers across the web have been worried about Microsoft Windows 8.
In a recent video(see below) released by the developers of Windows 8, they show the new ribbon UI, a lot like what is used on the Windows Mobile Phones (the Metro UI), but for a desktop, presumably with a touchscreen on it.
The thing that has a lot of people worried is that in the video, Jensen Harris, says that HTML5 and JavaScript will be used to make the desktop apps, instead of Microsoft's widely popular .NET Framework, WPF and Silverlight development tools.
