Our advisor recently purchased 2 new cortex units. Besides these cortex units we have one new cortex unit. This cortex unit has never been touched, and it was found inside a classroom lab kit we have. This classroom lab kit has been with us since March 2011 unopened.
My question is if there is a difference between this cortex unit and the one we have recently ordered?
The one in the box has the hump, which I assume that the new one will have.
Is there any benefits to use one over the other. (More easier to stall motors on one unit over the other, increased connectivity, mechanical improvements, etc.)
I know it may sound silly, but if you had to choose between the new cortex unit from March 2011 and the new cortex unit that will arrive shortly, which one would you rather pick?
