At the CES, Microsoft's expected to show off its first public glimpse of Windows 8., and already there're a couple of new Windows 8 codenames circulating.
Paul Thurrott published a few tidbits about "Mosh" and "Jupiter". Mosh is the alleged tile-based shell which'll be part of Windows 8, and "Jupiter" is a new application model for Windows 8.
The tile-based shell concept is intriguing, a search for "Mosh" search terms pointing to a Windows8Beta page about the Windows 8 UI, lending at least some credence to the idea that "Mosh" is real. If Microsoft does add a tile-based interface to Windows 8, Microsoft will go some way toward addressing the folks, like yours truly, who really wanted to see a Windows Phone 7 experience on tablets and slates, rather than a pure Windows one. Microsoft so far has balked at allowing OEMs to port the WP operating system to slates and tablets, requiring them to use full-fledged Windows, instead.
As for Jupiter, Thurrott post:
"The (Win 8) app store will provide access to new, Silverlight based "immersive" apps that're deployed as AppX packages (.appx). The Windows and Office teams are betting very heavily on this new app type, according to my source, and development has already begun using a beta version of Visual Studio 2012. These apps can be written in C#, Visual Basic, and even C++."
