Well, who in the hell actually opens up their internet browser and types a computer name into the address bar?
The vast majority of people (non-techies) don't distinguish between the address bar and the search bar.
There's a reason why type-in domains are so valuable. Some http://money.cnn.com/2005/11/30/technology/domains_biz20_1205/index.htm estimates claim this represents "10 percent of the global paid search market".
