I got the Garmin Nuvi 1390LMT from a RadioShack on Market Street in San Francisco, the nearest electronics store to my Chancellor Hotel, as they're hard to find. The helpful assistant recommended it, since it comes with lifetime maps.
On 20th December 2011, SingTel launched Singapore's first LTE service, available to both consumer and business users. Initially it supports only USB dongle modems, with LTE smartphones and tablets to come once they're more widely available.
I visited the official Timbuk2 retail store in San Francisco, at 506 Hayes Street, where the staff were friendly and the service excellent. I picked up four bags, the Command Messenger, Q Backpack 2011, and two Hidden Messengers, spending US$279.
