If you’re particularly fond of the kinetic scrolling functionality of iPhone and Zune 3.0, then you’ve to get your hands dirty on Windows 7 since kinetic scrolling is now operating-system wide. The feature, officially implemented as “Panning” — what this feature does Windows 7 M3 Pre-beta build 6801 is allow you to use your fingers to “pan” or scroll any element with a scrollbar. The obvious examples include the start menu, Notepad and the help files. At the time of writing, browser windows including both IE and Firefox are not compatible which I assume is because the browsers implement their own scrolling behavior (ie. smoothscroll). And just like most other kinetic scrolling implementations, if you reach the barriers abruptly it’ll move the entire window as if you were pulling on it. There is also some inertia so content keeps scrolling if you swipe your finger.
