Google has come a long way since 1998. It has become a Microsoft of the Web due to its long list of services including Gmail, Orkut, Google Earth, Google Desktop, Blogger, Google Search, Google Adsense, Google Talk and so on. If it continues to excel like this, than we can expect its search engine to be something like this in 2084 (If we were alive by that time :) )

Google in 2084

Weird ! It will even search ur brain :)
But the homepage will be Black and White :d
