This is really off topic, but the guy that gave me my PowerBook said that video editing was moving back to desktops (this was late 2009, early 2010). I went to his house approximately five months ago, and guess what his editing rig was. A 2012 MacBook Pro with Retina.
That's impossible. Everyone knows serious video editing can only be done on a 5K iMac or Mac Pro

Re: The scroll ball on the Magic Mouse.
This is one of my favorite mice. I've had this issue a few times. My resolution is to do one of two things. You can scroll the ball right or left for a few tries and then try scrolling again. Or press down hard on the ball and then scroll it in the direction it's not working in.
What happens is that the ball picks up oils from our fingers and loses contact. These methods I describe 'roughen' the ball up a little so contact is re-established.
Don't you mean "Mighty Mouse"? Two different mice you know.
I'll have to open it up at some point and see if I can fix the scroll ball. I agree it's not a bad mouse.
