What is Raspberry Pi? Simply it is a computer about as powerful than the average smartphone with about the same form factor (a bit bigger due to the additional ports) and power requirements. With the addition of four USB ports (which will connect to our mount, camera, etc), and ethernet port (plus wifi and HDMI output), it has all the capability we need.

- Minimal power requirements (a cell phone charger will power the Pi)
- Minimal cost (<$100 worst case for a RaspberryPi with case and microSD card)
- Low cost means we can easily afford to have a spare Pi on site ready to go as a backup in case the main one fails
- Better reliability (in theory) since there are fewer physical components to fail
Of course, we will have a full sized computer (donated!) on hand in case we need it...but with our Pi, I have a feeling we won't be needing it too much :).
