A lot of people have complained about the screen orientation lock being moved from an external switch to a button on the screen. After using it a bit I have concluded that I like it. I use my iPad a lot in my living room and bedroom, in both of which I have the lights turned down. I found that because of the case that I have the iPad in I was always physically looking for the switch to see which way I had to go with it to lock or unlock the screen. With the lock on the screen I can easily see it and do what I want with it. And to get to it is only a couple of taps and a swipe.
