I recently got this mouse to go along with my laptop and it was huge - I called it a "rat" rather than a mouse. It was a trackball. It didn't fit comfortably in my hand and the only reason I bought it is that it was on clearance (yeah - red flag). I couldn't left-click with my thumb easily. I had to hold it funny and it turned out to be just a waste of money. I bought another one - kensington - and it's great. But I'm wondering if anyone else every got a mouse that just was too big?
