Microsoft says none of these are available on the Mac. It's true, the Jump List feature that "opens files in just two clicks from the task bar" is not called that on the Mac, and only requires one click under Recent Items under the Apple menu. There are also other features unique to both Windows and the Mac. But are these four features really the strongest Microsoft can include in its sales pitch training for Windows 7? Apple calls most of Snow Leopard's new features "refinements," but may are more significant and useful.
When you have an inferior product (Win 7) you have to resort to lies to market it.
