Regarding the Nexus one that's surprising and disappointing. I was under the impression that the Nexus line used vanilla android (no device manufacturer or service provider customizations) and would be update-able as long as the hardware could handle the new OS.

Samsung Galaxy Nexus (GT-I9250) has Google's logo on it was the first such example. It shipped with Android 4.0 and the last version supported is 4.3, 20 months of software updates.
