I went through a couple of rough drafts before I had a small design I was happy with. As to why I didn't fully extend the board under the serial port: I had some size constraints (I had to be under 'x' amount of square inches) so anything helped :) Aesthetically I would've preferred the PCB to extend the full length under the DB9 connector.
And here are the circuit boards as they came in from OshPark
