I picked up the Razr at Costco yesterday and I must say that I am very impressed. I was very critical of the Bionic screen, but the Razr is a huge improvement. If you look very close, specifically at the 4g LTE logo, you can still see some pixels, but it's not noticeable from normal viewing distance like it was on the Bionic. I also don't have a problem with the dim screen like some have mentioned. After first checking out the Razr at a Verizon store, when I looked at my OG Droid it was nowhere near the quality of the Razr. While in the store we compared it to my wife's TB, and the Razr was just as bright, if not brighter. Also, while I thought the size was more of a gimmick, I am truly amazed by how light and thin this phone is. Even though it's larger than the OG Droid, it fits in my pocket so much better, and honestly I hardly notice it is there.
All that said, I am still heavily in the Nexus camp. I was very honest with the guy at Costco and inquired about their exchange/warranty policy. He assured me that I could exchange for the Nexus *if they get it* within 90 days. If Costco never carries the Nexus, or it doesn't drop in 90 days, I have no issues about my decision. The Razr is a great device and I will be happy regardless.
EDIT: I just wanted to add that anyone with unlimited data picking up a device at Costco (this might go for anywhere), be sure to make it known you want to keep unlimited data. The guy who helped me was awesome and verified, but he said that he was prompted to switch me to a 4GB 'promotion' but he knew well enough to bypass this.
