I have loved the Logitech TrackMan trackballs, particularly the "marble" versions. I have used almost every version they have produced. This particular model of the famous Marble is my favorite - precise thumb control of the ball, and easy fingering of the buttons and scroll wheel, all combined with a perfect ergonomic design that allows hours of comfortable use.

When I went to a Mac recently, I reluctantly but dutifully got a Mac power mouse. BIG mistake. I hate, hate, hate using a mouse! So I hooked my old TrackMan up to the Mac keyboard and - Voila! - my right hand was happy again. And I was effortlessly zooming around the screen. And joyfully experiencing, once again, the superiority of a right-click context menu (that Control-Click BS is something I never will understand about Macs).

Since I have become a Mac devotee and would never go back to PC - especially now that I found I could use my beloved trackball - I decided to treat myself to the convenience of the new cordless TrackMan. Same great product I'd been using for years, just without the "string." Others might complain about the size of the transmitter and the length of the cord that attaches it to the computer, but it is easily concealed. My keyboard drawer is delightfully free of clutter, with only my new, ultra-thin Mac keyboard and my cordless TrackMan. Life is sweet!

If you, like me, prefer a trackball to a mouse, you will love this cordless version. If you are a regular mouse user, I urge you to consider the liberating experience of keeping your hand in one place and letting "your fingers do the walking."
