Engadget: Joshua Topolsky got a hold of the Nexus One and posted up a video of his initial experience:
One thing I must mention again is the 3.7-inch AMOLED display on the Nexus One. I haven’t seen it with my own eyes but I believe it will be significantly better than the iPhone’s 3.5-inch LCD. If you are not inclined to unlock your iPhone and move on over to T-Mobile because of your experience with AT&T in your area, the Nexus One looks to be one very good option.
