The Motorola Droid was backed by the largest marketing campaign of any Android phone and it appears to be a success for everyone involved. Google got their mobile operating system on the largest carrier in the U.S., Motorola became relevant again, and Verizon gained a true competitor to the iPhone.

The Droid sold over a million units and it is still going. It now represents over 20 percent of the Android devices that have accessed Android Market, according to the last platform versions report from Google.

Engadget just held their annual readers choice awards and the Motorola Droid was the big winner for 2009. I love Engadget and their Android coverage has been improving, but I still get the feeling they are an Apple leaning blog. It looks like the Droid is the new cool kid in school, because it beat out the iPhone 3Gs in several categories.

The Motorola Droid narrowly beat out the iPhone 3GS in Gadget of the Year and Smartphone of the Year and also took home the GPS Device of the Year (crushed the competition).

It is kind of ironic that Motorola’s best selling Android device did not include their Motoblur service which they have been trying to push. They allowed Google to dictate the software choices for the Droid (stock Android) in exchange for being the first handset maker to offer a phone with Android 2.0. Motorola is expected to participate in Google’s phone store, so it will be interesting to see if they launch another device with plain old vanilla Android.
