I'm considering it, but only because the Nexus was the phone I originally planned on getting and "settled" for the Razr last month when my OG Droid was having issues. That said, I have been very happy with the Razr. I actually think Moto did a great job with Blur. It's subtle, unlike Sense, and very snappy. I also don't notice the bloatware because you can uninstall some of the programs, and hide the rest. I also like how thin the Razr is, as it feels like nothing in my pocket.
However, I am very intrigued by ICS (yes, I realize the Razr will get it at some point), and I want to see how the Nexus feels in my hand. While I love how slim the Razr is, it is a little wide. I also think that I am stuck on the fact that I have been holding out for the Nexus for a while, and now that it is finally released I want to give it a chance. I intentionally purchased my Razr at Costco for the 90 day exchange policy, so while I may switch, I fully intend to take all the time I need to make sure it's the right device for me. I am very happy with the Razr and it will take great reviews and personal experience to get me to switch.
