I just played with the Razr at the Verizon store. I liked it but, not as much as I thought I would. I had the same feeling initially about the Nexus S so, overall I'd probably like it, once I got more time with it. It's certainly very thin and light. It also seems sturdy. I couldn't feel the Kevlar back because of the coating they had on it in the store.
The cameras seems a little better than the bionic's but, still not on par with the iphone 4 as far as I could tell. I really like the screen, it really looked good and, was probably my favorite thing about the phone. I watched a video and, it looked real good.
Everything else was similar to the Bionic as far as the OS and Motoblur was concerned. I overheard a guy asking about the Galaxy Nexus and, the sales rep said, they were getting it but, had no idea when.
