"Apple's giving developers a preview of the next version of Mac OS X today called Mountain Lion. The software, due out this summer, once again brings over features from Apple's iOS."
Facebook today announced the App Center, a new place to find apps - but not just Facebook apps like FarmVille. The App Center includes both free and paid Facebook apps, as well as HTML5 apps that exist within the Facebook app itself. Android, iOS, and "desktop" apps will also be included as long as they integrate with Facebook.
