Yeah I think that was the mistake they made. People should be thinking of their phone as just a Samsung phone or an HTC phone, not an Android phone. The perception should be that the phones "tie in" with Google services, not that the phone itself is actually a Google product. That's how Google tries to frame it, but it's difficult because it's much easier for the various manufacturers to "tie in" with Google if they all run similar operating systems, which was the whole point of Android in the first place...a common platform which manufacturers could build on and still tie in to the Google ecosystem. Google has to provide that common platform while making it clear to the consumer that they don't have a Google or Android phone, but a Samsung/HTC/whatever phone.
Google doesn't have control over it by design, and it's a good model for them. They want the manufacturers to deal with the end users...they just need the data so they can sell it to advertisers. The Android brand shouldn't exist, it should be a ghost that only techies know about. It seems like Google recognizes this and is trying to shift the focus onto other brands (e.g. Nexus).
