Try doing that on a touchpad(is that the word?). First when you click the circle, it moves a couple of cm, then you have to try to move your fingertip slooowly towards the time you want to start from. I mean, come on people... what are we doing here?
Right. Jokes aside, I'm currently using a pretty new MBP. Still not understanding the problem here. How is the circle a good idea? There must be some technical reason for why they went with it. I can't imagine anyone testing it out for more than 5 minutes before thinking "Yep, this clearly sucks".
