So, thanks to Chief and Unforgiven, I got my OTA done! I had to replace the recovery.img file (thanks so much Unforgiven for the link!) and it worked perfectly after that. I have to root again, but no biggy (I hope!)
BB and everyone - grats on hitting 15K! Wow, this either shows how popular the Nexus still is, and/or we just have a bunch of talkers...lol.
Off to do some rooting!
