One good place to look for what might be coming in Windows 7 is an early planned feature list of Windows 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?
Location Awareness, according to the Microsoft document:
collects computer location data such as address, position, building/floor/room, and stores it locally in the WinFS store. It also collects data that helps to determine the location information of your computer, but is not directly useful as location information itself, such as: MAC addresses of access points near your computer and the IP address of the subnet and default gateway to which you are connected. It collects data from you, from the active directory, from wireless zeroconfig, and from IPhelper.
