I finally got over my initial negative experience with Google's ordering process and placed another order. Very nice tablet. Pretty much a larger version of my Motorola Droid Bionic, so I use the Nexus at home instead of the Droid for quick email and look-ups.
The Nexus refuses to sync my calendar, a problem documented elsewhere.
I stumbled into the facial recognition security feature and have been using it successfully. Very nice. Even delightful.
Haven't figured out if/how I can make free Google Voice/Talk calls.
