I get the same message as Samalex. My speculation may be a WAG, but the Bay Area is the second largest port for Asian import entries, and Los Angeles is #1. Assuming Asus makes the N7 in the Philippines or China, N7 shipments will enter one of those two ports, and be stored in an Asus or Google warehouse. Google and Asus HQs are both in the Bay Area, in Mountain View and Fremont, CA, respectively. The main UPS distribution facility in the Bay Area is in Oakland, CA, 40 minutes from me.
So, it's a good guess my N7 is in my local UPS station already, and will be on my doorstep tomorrow.
