The reason for the Emulate IE7 button on IE8 is because Microsoft is always behind on what they should do. For instance, you have a crappy browser, IE6 so you decide to force people to update but, and only if, you have a valid version of windows. So obviously a lot of people do not update their browser. Of course Microsoft realizes that this is a mistake and releases IE7 without any genuine check so that everybody can upgrade but there’s still some people that do not want to and we are just left to wonder, why if they force other stupid updates they don’t get everybody to IE7 once and for all.

Now with IE8 coming this year, it looks like IE7 will still be around which means that developers will have to use the IE7 button when testing their websites to make sure it looks correct on both versions and after that, use Multiple IE’s to be able to test on IE6.

Thanks again Microsoft, for making the Web DEveloper life so more interesting.
