So I turned BAR off on my iPad when I was tethering to save data. I'm back on wifi now but will be tethering again soon. One thing I've noticed tho is that I can't think of a single instance of where I've been inconvenienced or had to wait due to having BAR off. BAR strikes me as a little 'unApple'. I don't really know what it does and think iOS should know what to do for the best. Anyway, can anyone provide specific examples of how BAR switched on actually improves things? Maybe I'm missing it but I just don't see any tangible benefit or any improved readiness within apps when it's on.
