Had "braindead" been said without further explanation, Asa, that would have been rude. But since you explained where your opinion came from, readers should be able to make up their own minds without feeling jilted. I've always admired your adherence to relaying complete thoughts here on ATP, something that is rather rare on chitchat forums.
Anyone finding themselves in your shoes and not coming to the same conclusion, well, I would question their cognitive reasoning, too. That said, I'm happy with my proprietary batteries and camera, precisely because I am not in your shoes.
