This you see here is the Apple Mighty Mouse. I hated this thing when I first used it(no right click?!?). However, I have been using Photoshop more and more and it's benefit is shining through. That trackball that allows me to side-scroll is really smooth and easy to use. It makes navigating photos that I'm zoomed in on a lot easier. There's rumors of a new Mighty Mouse after a filing hit the FCC, so we'll see if the new one will be better or worse(no click at all?!?).
