One good place to look for what might be coming in Windows 7 is an early planned feature list of Vista (then called Longhorn) back in 2003. If one intriguing feature, called Location Awareness, makes its way into Windows 7, it could track your every move...and that could be a good thing.
Microsoft described Location Awareness, along with a host of other planned features, in a document called the Windows "Longhorn" Pre-Release Privacy Statement that detailed to beta testers Longhorn"s expected data collection and use. (Thanks to istartedsomething for uncovering this document and its relation to another potential Windows 7 feature, HomeGroup.) Many of these features never made it into Vista --- remember WinFS anyone?
