I was helping somebody set up a LogMeIn account the other day, and when we got around to testing, I figured I'd walk her through it. I told her to go to logmein.com. She opened up Internet Explorer, clicked in the little Google search box on whatever toolbar it was on, entered "www.logmein.com" in the search box, clicked Search, and then actually pondered for a second on which of the results she wanted to use.
Then, she clicked on the sponsored LogMeIn link.
I pointed out that she could have just entered the address in the address bar to begin with, since she went to the trouble of typing the whole thing, including the "www". I got sort of a blank look in return.
It makes me want to buy some Google stock.
