Just as you state this. I have to disagree. Not saying that I have empirical data to back it up; I just have to go by my experience. And apparently, our experiences differ. I'm not talking about drastic changes; I'm talking about one big enough for me to see a difference in terms of hours before I have to recharge as opposed to lasting all day. Scientific or logic evidence? No. But as it stands, you don't either. Some folks are having issues with ssh "sticking" (search for it) or some other services that are only active during dev mode that are somewhat problematic. Not all, just some. And I'm one of those "some". That's my take.
