The power and top speed upgrade exceeds the original specifications, and we have quadrupled the warranty coverage. This would be similar to your car getting more acceleration, more braking, a higher top speed, and a longer warranty, all remotely and for free.
Firmware update capability should be the norm, and to our knowledge we are the first and only board that can do this.
Just take a PC... Windows is it's firmware and if you want to upgrade it, then you have to pay. (Or, switch to Linux).
Or take some cars which are different models, with different power/torque ratings, but mechanically they are the same - the only difference is made in the MCU software. Or cars with their maximum speed locked and only unlocked after paying a nice sum of money (iirc it was the VW Golf GTI).
The difference is a PC is an open and well documented platform that anyone can write software for. This board and other embedded devices typically don't provide the details needed to implement alternative firmwares. That is the difference between windows on a PC and firmware on an embedded device.
