Considering he had a device before release day, he thought he had the official firmware but was mistaken, he might have come off a bit too sure, but nowhere near as sure as the apologizers that said for a fact that he had a stolen/prototype/broken unit. With bad firmware. That he was using wrong. All sorts of excuses. Which they had and still do not have anything to back up with. I understand perfectly well that he got provoked by that, and it would bring out stubbornness in anyone.

His device was hardly the only one that had problems, now, was it? The first batch had a fair amount of problems including reboots, if I understand correctly. And that was after they had a chance to fix the older code in Eldars unit. Also, remember that Eldar was not indoctrinated with "do not install software from extras/testing/devel" because it is non-optified Evil".

Fact is, he brought to the table news that were discredited every step on the way, but turned out to be spot on. Then he came with a very positive review, all the sudden he was a hero. Then he reported troubles, and he turned into some sort of antijeebus.

So, go ahead and hate him, but that says more about you than him.
