I bought my new Nexie (as I like to call it) last Thursday at T-mobile. I am an existing T-Mobile customer but I was willing to pay the $550 (including tax) to get my Nexie!
It is a fantastic device that does everything at about the same speed my old Blackberry did, but hey this is the Nexus One (by Google, people), so it's better.
Sure the 3G is not working, but I'm sure it will start soon, Google would not leave it's customers hanging, right? And since I am already a T-Mobile customer, I am used to crappy service and dropped calls.
I certainly don't mind e-mailing my Nexie questions to Google, I am sure they will get back to me sometime soon. They are busy people, you know.
Google's company motto is "don't be evil" so they couldn't be evil to their customers, that would be hypocritical, and that is one thing that a billion dollar company would never be.
So my vote for the Greatest Smart Phone Ever is the love of my life, my Nexie.
