What you've said is funny because your words could just as easily have come from a Windows 8 PR release. They love tasks! They're all about them! Have you used Metro? The main screen isn't just for launching applications. Tiles can be simple app-openers, or they can display information, or they can link to "hubs", or they can be file/website shortcuts.
