I took my Nexus to a local mall (Viewmont Mall near Scranton, PA). I took a screen shot of the dBm/asu just prior to each speed test I took. Below are the results. I also tested my nexus and the rezound and razr they had in the mall. The results of those comparisons are at the end.
Short summary: after this trip, I am
definitely inclined to believe two things. 1) the nexus performs well even with a "bad" signal, but 2) seems to drop to 3G more easily than the other phones (based on conversations with the CSRs. they wouldn't let me take a rezound to walk around the mall to test lol).
9659/678 3:36 pm -141 dBm / 0 asu
6279/935 3:40 pm -113 dBm / 27 asu
8878/1390 3:43 pm -105 dBm / 35 asu
6181/531 3:54 pm -110 dBm / 30 asu
5149/1616 4:01 pm -112 dBm / 28 asu

I was particularly impressed that in even the worst case scenario (inside the middle of Macy's with a -141 dBm/0asu signal, I still pulled nearly 10 mbps down and 678 kbps up. The
only time I dropped to 3G walking throughout the mall was when I walked into the middle of the Old Navy store. Even inside Sears, I was holding a signal ~-105:-113, but still getting at least 6 Mbps there.
Also, just an observation. It seems the low signal affects the upstream much more than the downstream. At least on speed tests.
Despite the signal dropping from 4G to 3G going into my in-laws' house, that seems to be a combination of a fairly weak signal and an old house with aluminum siding acting as a faraday cage.
As for the comparison at the mall VZW, I tested their 3 phones and the nexus was getting about 27 Mbps/12 Mbps. The rezound was barely able to get to 6-7 Mbps down and was about 9-10 Mbps up. The razr completely crapped itself and lost 4G /and/ 3G signal. I toggled airplane mode and then re-tested and it got about 22 Mbps down and 13 Mbps up. So it seems to perform closer to the nexus. The rezound semes to be slow in comparison. Who knows what kind of signal it had, but just based on raw speed tests, it is getting spanked by the nexus.
This brief experiment at the mall has renewed my faith in the nexus and I hope the 4G -> 3G drop off can be fixed in software by adjusting the threshold that it senses.
Also something I observed in comparing their nexus to mine. Their screen has a lot of yellow tinting. I couldn't see the same tinting in the upper left corner of the keyboard in portrait mode like I see on mine, but that was because the majority of their screen had the yellow tint/hue.
I pulled up a fullscreen gray image on both mine and theirs. Mine had more banding that I could see, but it's still subtle on mine. Their gray had a slight yellow hue, while mine had a slight yellow/blue hue.
I have a feeling AMOLED screens just have some variance. I was told on irc last night it's normal for AMOLED and they will kind of "settle in". Hopefully that happens by 1/15
Anyway, figured I would pass along my real-world experience with the nexus in what appears to be a strong 4G area (outside the mall, I get full bars and -75 to -83 dBm on LTE).
