That's one reason I use a trackball type here since I don't actualy have the space on the desk to move a mouse around. Plus when first getting the MS Trackball Explorer used here the optical models were just being seen for the first time.
That's a larger size model typical of MS models over Logitech. The logitech models are reliable but for those with small hands. When you have larger hands with longer fingers you don't want to pressing two buttons at the same time!
