Query: The Logitech LX3: a great mouse

It does what it's supposed to do. That's all I wanted. My main concern was to replace my Mighty Moue, which had horizontal scrolling. I love Apple computers, but the Mighty Mouse has a problem. The scrolling mechanism gets dirty and stops working. it can be cleaned, but eventually, may stop working, regardless. The Logitech is the answer. it was a relief going back to the more familiar scroll wheel. Gently push it sideways for horizontal scrolling. The only thing missing is the expose side buttons, but I don't mind hitting F9 instead - an insignificant trade-off for a superior product. Thanks, Logitech, for the best mouse I've ever used!
