My upgrade is available on Monday (11/14) and I'm between getting the RAZR or the Bionic. I like the feel of the Bionic compared to the OG Droid, but the RAZR is definitely a very sexy device. Bigger wow factor with the RAZR and it fits in my jeans front pocket nicely. I'm more worried about what a ski crash might do and if the Bionic would be a more sturdy phone. I rooted my OG Droid, but I don't think I will need to unless ICS gets delayed for the RAZR.
I think on just a cool factor alone, the RAZR beats the Bionic. I don't like the Nexus Prime's plastic backside. The OG Droid was a tank, and still is.
