I’ve posted my full-length Google Nexus One review on MobileBurn.com. You should jump over there and give it a read (and watch the videos, if you haven’t watched them here already).
In short, I like the device, but don’t love it. Text input is a big weakness, as is the 3G data. The 3.7-inch AMOLED touchscreen, 1GHz CPU, and awesome call audio quality are spot on the money, though.
