This is why I am a fan of the Teensy3... It's a Freescale micro based on 
ARM cortex, and fast, low power, etc.

However, I happened to have an Arduino sitting in front of me on the 
table on Saturday when this started.

The computer you've got is better than the one you have to order and 
wait for.
