I am neither surprised nor upset by Bob's comments. And I am entirely sympathetic to his concerns about possible damage caused by mis-applied (in the technical sense) software. We know its power to do good through optimisation, surely we should be cogniscent of the reverse!
The result may be that we have to either cart our kit to dealers for a s/w upgrade (no doubt with a charge) or have to receive software in some form of license-controled medium (also, no doubt, with a charge). And perhaps the firmwares are now being modified to include a water-mark to identify if the code has been modified in an uncontrolled manner?
I for one would be circumspect about buying a previously-owned unit that had been messed with in this manner. Am I alone?
