Got mine last year. Can't smile in passport photos anymore. Quick and easy photos at FedEx Office (formerly Kinkos).

Went through USPS. The real freak-out for me was when they took our original documents. We received our passports, but without getting back the originals. We called and found out that the original documents are returned through a different process. Got everything back, so no worries.

Just recently found out that the passport was really handy for I-9 verification for a new job.
