Hi Mt Spokane.
I do agree mostly with what you say but I thought the whole idea of computers was to make our lives easier, not just for reading CR Forum!
Should it not be possible to run hundreds of thousands of permutation simulations on computers in very short periods of time, computers are great at chomping through numbers, its what they do best.
I know that there will still be a chance of some random permutation of settings that will cause a conflict , but that should be an incredibly small chance, not in numbers that would cause a withdrawal of an upgrade?
It is at least good that the update can be rolled back to restore the cameras to useful condition.
I wish they'd test their stuff better before release.
Of course, there are a near infinite number of things that could go wrong, so it would take a near infinite amount of time to test them all. Unfortunately, several thousand users can run more tests in a week than 10 testers working for a year.
