I hope others help make this decision.  I actually have
nothing vested in this.  I am just making some suggestions.  

Another one would be to move the signals on pin 3 through 7 up one pin
so that the n/c is on pin 7.  You still have dealt with the saftey
issues of accidentally swapping/shorting power to ground and now if
anyone wants to save space (and give up the polarized key) they can go
to a 6 pin connector.  It is not uncommon that a tiny design needs to
save all the space they can.  And that is what these MCUs are all
about is *tiny*, right? 

pin 1 -  3.3V    /RST  - pin 2
pin 3 -  RxD     P0.14 - pin 4
pin 5 -  0v      TxD   - pin 6
pin 7 -  n/c     key   - pin 8

All of these are just ideas.  But I promise I will stop.  So pick
one... :)
