System images have long been used in corporate network environments for simultaneously restoring scores of computers to their original states. The same technique also works well on the small scale. Many people complain about their computers becoming slow over time, at which point, reformatting and reinstalling the operating systems becomes the only option. This is where imaging saves the day. The average user doesn't want to spend the time to back up all of their data and reinstall all of their programs, a process that can take days. A system image is essentially a complete copy of your system state at the time it is made. When the image is written back to the drive, your system will be exactly the way it was when you made the image. I suggest making an image a week to a month after getting a new computer, this way you have time to install programs and tweak settings to your liking.
