I had read they had a "Dream" android phone prototype they were working on that was blackberry like [1]. There was also rumored to be a second one that was more iPhone like slated for down the line, but when the Apple demo happened Google immediately scrapped their blackberry like phone and the second one became the first.

Interesting that Google recognized the importance and adapted quickly while Ballmer laughed it off: https://www.youtube.com/watch?v=eywi0h_Y5_U

If you walk through the new London Google office by kings cross, you can see the original android phone right by their restaurant. It looked just like a blackberry / Nokia E62..
