Ok, I guess there might be just about nothing more annoying to me in technological life than when my android cell phone doesn't "accept" swipe gestures I am doing e.g. to unlock it. As if the thing being gestured away got a lot "heavier", it moves only a little and then rebounds back. I have to do it like 4 times and then it goes. "Maybe I curse too much in my head." Or, speaking for myself, out loud.
