These days there are plenty of reasons to have a second computer to do all those technologically “dangerous” tasks that could compromise a computer’s operating system integrity.
You might be downloading new software, either legally or illegally, which could contain spyware or viruses that could cause your PC or Mac to grind to a halt or leak personal and financial information.
Personal privacy is also another good reason for second computer, especially when you have family members or work colleges accessing your computer. Nobody needs to know about the tell-tale novel you are writing or the “special interest” websites you like to visit and download software or media from.

Virtually “Windows”
Microsoft have been providing their users with some fairly reliable and free virtualisation technology for desktop machines called Virtual PC. With the release of Windows 7, users can now download a free copy of Windows XP (or install your own copy of any Windows version) and run their “legacy” applications in a virtual environment hosted by your laptop or desktop.
All Windows virtual machines save their operating system and user data within a virtual hard drive container. This virtual drive is stored as a single [large] file on your host machine, much like a Zip or RAR archive …
This means that you can test out new or dubious software in a protected, virtual environment that doesn’t effect your desktop environment. If there is a problem then you can simply delete the virtual image and copy in a new virtual operating system image to start again.
A virtual life for the average user …
Traditionally organisations have used virtual environments to test their software under controlled conditions (usually with Virtual Server or Hyper-V), but for a regular user with a few odds and ends to hide a virtual machine can help then lead a relatively secret virtual life.
