I certainly agree with Bill Norrie. Windows 8 changes literally everything! It is the future though, and is oriented toward touch screen tablets. I will wait as long as I can before using Windows 8. I'm not all that sure I want my stuff stored in the "clouds". I use Windows 7 Professional, and use the XP mode for a lot of stuff. I also keep a laptop with XP for all the software that needs to interface with the KN7000. It has wireless internet capability but I don't use it. I'm not concerned with loss of support for a computer that doesn't access the Internet.
