I was told by a multi-vendor phone booth employee that none of the
storefronts actually stock the Nexus One so that you end up getting it from
Google in any case.  He claimed the only difference was that whether you are
buying a T-Mobile Nexus One or an unlocked Nexus One.

I do not know if that is true or not as I later went to a T-Mobile store to
check it out and there were too many customers so I did not want to wait for
a sales person.  However, I did a thorough look around and not only found
none on display but also found no sign-age mentioning the Nexus One.
