<b>Not: Google Nexus One</b>
The iPhone was a hit. The BlackBerry is still popular. But the Google's foray into mobile...not so much.
In the same amount of time it took Apple to sell 1 million iPhones, Google sold a measley 135,000 units of its Nexus One. On July 16, Google announced that it received its final order from the phone's manufacturer, discontinuing the phone in the U.S. The Nexus One will still be sold in Europe and Korea.
