Read level access to the root of the drive would provide harvesting capabilities. Then again, so does having a FAT32 bootcamp partition within OSX. Just like I enjoy being able to access my whole windows file system within OSX, I enjoy having the same capabilities within Windows. I do agree that users should be aware, and when this comes out of beta that it should be right there in the help file for that section. I'm not worried about harvesting though. Very little leaves my system without my knowedge, and even less makes it out of my network at home. When i'm in the office where security budgets are higher than my home network, control is even tighter. I doubt the same holds true for most people, so the option to restrict to just the users home folder would be appropriate. Then it would be similiar to only having access to Windows 'My Documents' (plus a little more application stuff) in Windows. Either way, people do need to be aware that running a computer presents security risks. Not that OSX is secure, but MS does have the most malware associated with it, and users need to understand the risk they are undertaking anytime they operate within windows.
