the part I love is that it lets your hand be in a natural position. You know, where it's like at a slightly angled position? It's nice, it has an indentation where your though is, and it slopes up for your side of the pinky and stuff. I can't believe how good it feels. On top of that, it has super-smooth skids so it glides like it's on air. I love this thing. my mom got the same model for her iMac. We were looking at the mice at target to replace her mighty mouse which was having problems. But when we saw this, i was talking to her about the types of mice.

I laid my hands on this one and it was love at first touch. Got it home, and I haven't stopped using it
