I’ve been running the beta version since I started running the beta version of Windows 7. I’ve been VERY happy with NIS 2010. It is a huge improvement over the previous bloated, slow, and buggy released of Norton\Symantec’s security software in the 2000s. Symantec rewrote NIS from the ground up with the 2009 version. The 2010 version support Windows 7 and has some further improvements.
My favorite feature is the Identity Safe, like RoboForm it lets you save your username & passwords to all websites and "cards" to auto-fill sites. I keep a USB drive in my primary computer and store my info on it. When I travel I take the USB drive and put it in the laptop, or save the file locally and restore the info from it.
