well I was sitting with it last night, getting a feel for it when I noticed the scroll wheel just spins. you could get through all the Apple T's & C's with just one swipe of the wheel. which presented a problem for me cause there's no way I'm getting used to that. then I thought "well maybe it's broken, let me google this and find out if this is the way it's supposed to be". saw a couple of people complaining about the scroller so I schemed oh well now I'll just have to live with this
then I started wondering why the sensitivity button (just above the wheel) doesn't work either. and why is it such a heavy mechanical click....
so upon further inspection I discovered that the "sensitivity button" is actually a button that sets the scroll wheel to either free roll or notch roll (a term I just made up. patent pending.)
needless to say, I felt like a complete Malema at that stage
