 - can I put the GPS chip antenna on the board *and* allow for an SMA or other
   connector if we want it off-board?
 
+- changing the memory part from the SOIJ8 to the DFN8 would save about 2mm
+  in width, but that doesn't really help.
+- changing the 5V switcher from S8 to MS8 takes us from 5 tall to 3 tall, but
+  costs $0.30 more per piece and isn't stocked by Digikey.  Not worth it?
 
 - To Do List
 
-       - add serial connector back to schematic as optionally loaded part
+       + add serial connector back to schematic as optionally loaded part
        - move USB connector on PCB layout 80 mils in from board edge
-       - create PCB footprints for the GPS module and GPS antenna
+               - move yellow LED and passives closer to LiPo connector
+       - create PCB footprint for the GPS module 
+       - create PCB footprint for the GPS antenna
