If you develop websites then you will be well aware of the browser incompatibilities that cause a whole world of pain when you are trying to get something to look the same in all browsers.
Normally you will be testing against IE 6 or 7, Firefox and Safari. Due to IE 7 introducing a load of new behaviour you would also want to test it on IE 6 but you can't have two different versions of IE installed on any one PC. You could turn to a number of virtualised Windows instances with different versions of IE installed but that sounds like a lot of work to me ;-)
What if you could install a simple program and then have the following versions of IE available?:
- Internet Explorer 3.0
- Internet Explorer 4.01
- Internet Explorer 5.01
- Internet Explorer 5.5
- Internet Explorer 6.0
A blog post about installing multiple versions of IE on your PC by TredoSoft was the source of my information and it's got a lot more information about how it works and what doesn't.
