I would concur with John. The Jamis is a great bike, but if you have a flat 2 miler, then any bike will do the job. I used to ride an old 3 speed across town. My current bike looks like a beater, but is quite a nice ride.
The Jamis may travel a bit faster but will take longer to lockup every time. Use bolt-on wheels and seatpost, rather than QR and it will save alot of hassle at every lockup.
If you use the same lockup everyday, you can leave a hardened steel chain or armoured cable there and carry just a U lock or smaller cable.
