The reason for the Raspberry Pi is that it meets the following criteria:

1) Always available (MacBook may not be open and charged) 2) Energy efficient 3) No variable cost (as opposed to EC2 or Linode) 4) Very powerful when headless (Linux is better than OS X here)

It's not the most powerful backend but that wasn't really the point of this project. The point was that for $35 I added a dedicated Linux backend to my already awesome Transformer tablet.
