If google became a web host?

I was wondering, if google decided to become a web host would this have a severe impact on other hosting businesses? I mean, they have urchin now, they control the largest search engine on the internet and obviously have a huge impact on the market because of this.

I think it would probably have a larger impact for the bigger hosts, those such as 1and1 and more monopolised providers. I think google (what with its huge public presence) would probably be swamed with customers and ultimatly end up providing a second rate service in terms of support and reliability.

What do you think?
