I think some of this is driven from the google toolbar, which many people confuse with the address bar.

On a side note, what really boggles the mind is the number of searches for "google" or "google.com". According to the Keyword Tool, there were approximately 30mil exact searches for "google", and 7.4mil searches for "google.com"!

Some browsers will google search a term typed into the address bar if it is not a fully specified URL. On my system, if I just type "google" into an address bar, it directs me to the google search for "google".
