Thanks guys. Sorry, I haven't been tracking the releases closely enough, and Wikipedia let me down by not mentioning any of that stuff.
Still, the fact is that I - and many others, I'm sure - bought the GN specifically because it was a Nexus device. Now it seems we only get half of what makes a Nexus device - namely the lack of manufacturer skinning and stuff. We're not going to get the updates when they come out, and I would have assumed that this would be something that could have been figured out before the phone was released.
Basically, I'm upset because this phone is not what was promised. Verizon didn't care about it, Samsung didn't make full accessories for it, and we can't use the latest updates. After owning the G1 and the Nexus One, this is a big let-down.
