History-part 

Howdy! I noticed the following sentence in the History-section:

Ghost was the first disk cloning program.

Personally, I would prefer something like the following:

Ghost was one of the first commercially available disk cloning programs.

AFAIK, PowerQuest DriveImage/DriveCopy was also available around 1995/1998, although I am unable to find a quote or article on that right now. And who could forget dd, which has been around for ages and is utilized by g4u (mentioned in External Links).
