Under normal (non-competition usage) there is no reason for the functionality of the e-stop button. Unless it does something I'm unaware of, it disables the robot in the same way as the disable button. Disabling the robot until a power cycle serves little purpose other than to slow development down considerably.

I seem to remember a time where the space button disabled the robot and the enter button e-stopped the robot. This only changed last year, causing a fair amount of confusion among team members.
If both buttons are actually necessary, a way to either switch the mapping or select your own mapping would be extremely helpful.
See Mark's note below. That's a good question for the NI guys though: I'd like to know more about the differences too.

There is a fairly good argument why the mapping should not be changed. If everyone in FIRST knows the mapping, then anyone in FIRST can stop your robot by smacking the spacebar/enter key. Safety is one of those items where you have to take the attitude that, if it can happen, it will.
