[SoftwareBug2.0]

Here's a list of possible things one might want in a robot control system:

1) Processing speed
2) Code space
3) User-available RAM
4) IO capabilities
5) Radio bandwidth
6) Code download time
7) Clean programming interface
8) Durability
9) Software reliability
10) Radio connection reliability
11) Boot time
12) Price
13) Compactness

If you were designing a new robot controller for FIRST what would you prioritize?

(I've been inspired by the thread about the new control system and seeing the "FIRST team survival excercise" thread. )
