FWIW, I just spoke to a sales advisor in Palo Alto by phone to schedule a test drive at the Marietta store. I asked about the apparent slow down. He said the winter weather has played a major role, but that work is ramping back up. He also said that deployment will resume at a pace equivalent to, if not more rapid than, 4Q13. He assures that "coming soon" on the map is still good for the 3-6 month time frame. We'll see.
