Blackdog has came up with a tool to do searching on google and Bing simultaneously and compare the results on both. Its easy to make this kind of page via HTML..no rocket science. But the usability and presence of this page makes the life easy.

Some people might be thinking, why don't we open two windows (one for google and other for Bing) and then tile them vertically.. Then try that one too honey.. you are wasting your time on thinking about making your life easy somehow :-)
