Windows And yes, the stream of controlled Windows 8 leaks continues. This time around, Thurrot and Rivera have published a number of screenshots from Windows 8's brand-new tablet user interface, and surprise surprise, its built on Metro, the same design language that underpins Windows Phone 7. Windows 8 will also include its own PDF reader, Modern Reader, which also happens to be the first application packaged in Microsoft's new AppX format. Update: Long Zheng has some technical details on AppX, including this little tidbit: "The extensive list of properties signifies the comprehensive scope of this system to be the ideal deployment strategy for 'applications', in all essence of the word. In fact, the AppX format is universal enough so it appears to work for everything from native Win32 applications to framework-based applications and even *gasp* web applications. Games are also supported."

App scalability

That's one fine incentive for developers - write your application, and have it scale from phones to tablets to desktops. Apple already offers something similar, of course, so Microsoft is a tad bit late to the game.

They do? I must have missed a big announcement. Last I checked, you got to write your app once for OS X, and then rewrite the whole UI for iOS using a different framework. Sure, there's a third-party framework in development that will let you use iOS's UIKit APIs on OS X, but even that's not a complete solution, and it's not something offered by Apple.

Windows Phone 7 apps can share much more of their codebase with desktop OSes (Windows *and* Mac) via Silverlight. So Microsoft is already ahead in this area, and providing a common app distribution format will put them firmly in the lead.
