The Droid marked the point in time when Android really started to take off, first in US and then worldwide. With an aggressive tech oriented marketing, Verizon and Motorola wanted to attack the iPhone straight at its heart. The "iDon't" ads really resonated with a lot of people, especially those who would've been early adopters of new technology. They showed that Android does a lot of things that the iPhone couldn't it, and more than 3 years after that, that's still more true today than ever before.
Unfortunately, although they might've been cool for a while, the robot ads I think were pretty ineffective, because that message didn't really resonate with people, nor did they help explain what Android phones are all about. I think that's also when Motorola started to stagnated regarding their Android phone sales.
The Droid is still a powerful brand name today, and with a new type of marketing, Motorola might be able to recover what really made the Droid resonate with people. However, Motorola also has to keep in mind that they need devices that address to the mainstream market, too. Not everyone understands what all those specs mean, or what the latest version of Android does, so to be effective they need to portray those qualities properly in the new ads.
Motorola should be bought by Google soon, and then we might start seeing some of Google's great and emotional ads, like the one they've done for Search, Gmail and Google+. I expect to see a much better direction for Motorola, once Google is completely at the helm, starting with making all the phones as Google really envisioned them – with stock Android.
