The Motorola Droid, which was most likely referred to in the document is one such 'lead device.' The Motorola XOOM tablet is another. HTC also got preferential treatment early on. The only competitive advantage a lead device gets is that it can be in the stores soon after a new Android version is launched. Other partners have to test the new version and develop phones for it, which takes time. What's more, it is hardly evidence that Google will be favoring Motorola from now on.
