I'm pretty much in the same boat. Having had the Thunderbolt and the Incredible 2 as my last two phones, I've narrowed my next phone search down to the Razr and the Nexus (I'm kind of sick of Sense). To me, there are really only two pros to the Nexus (as far as my personal use goes)...and those are ICS out of the box and the ridiculously fast camera. Other than that, the Razr has the edge (no pun intended). To me, the Razr's positives are:
better construction (hate samsung's plastics)
thinner overall (even the gsm nexus is 8.9mm at it's thinnest point)
hdmi out
edgier design that I prefer
removable sd card
gorilla glass
So really the only thing that truly could be an issue is stock ICS. I believe that since the Razr is unlocked outside of the US, we'll be able to get it rooted and unlocked pretty quickly, to which we'll be able to go stock ICS without much trouble (hopefully). So that advantage is pretty much gone for the Nexus.
Anyway, this is my long winded thought process that led me to getting up at 5am PST to preorder this morning.
Now I wonder when it will arrive (hopefully before November 10th, lol).
