Google Verticals

At a glance it looks like Google is everywhere and taking control of every vertical market they enter. But from a ZD blog it actually turns out the things like Gmail only have 5% market share and rest of the Google Verticals such as Google Finance lag very far behind incombants like Yahoo Finance and Google Maps lag far behind Mpaquest. I was surprised to read that because I was under the impression that Google was rapidly gaining market share on all these areas with what I feel is often superior products. Interesting, so what IS Google's end game? I am more curious than ever.
