It took me a nearly a year to get used to it. I tried and quit a few times. What happened was after exposing myself to it enough times, I began to recognize uses for it as I shot. So I started turning it on when those needs came up. It started with macro. I'm one of the lonely few that use autofocus for macro. I'll either keep that single point right on the bug giving it full af-c or I might let go after getting focus and recompose, possibly tweaking by changing my distance. Much like if I had manually focused. Then I saw needs for it shooting wildlife. I thought of it as manual focus with power assist. Want to focus on a particular point? Aim and press the bb. Once focused let it go. Recompose if you need to. Need continuous focus? Then keep it pressed. I'm sure you know how to focus/recompose. With bbf, the time between focus and recompose can be infinite. Focus once on a distant subject and recompose all day without refocusing. Also good for anticipated action. Pre-focus on the spot and you are ready when the subject arrives.
Anyway, I'm not trying to convert you, my point is really just to say that once I had a feel for this bbf tool in the back of my mind, I began to see uses where it could help me out even though I wasn't thrilled with it at first. Eventually my shooting adapted to this new found tool. Now its second nature and I feel all screwed up without it.
