Logitech cordless optical trackman

If you are like me, plucking and clicking away at a compute most of the time the last thing you need is a overworked index finger. Drawing with the traditional mice is tremendously hard on your right index finger with the excessive amount of pointing and orienting.

Ok. Take a look at this picture. You probably think, and rightly so, that the mouse is indeed "cordless"

However after I paid 55 bucks or so, waited a few weeks, and finally opened the box I got more than what I bargained for. The mouse has a receiver that's the size of a traditional mouse and (gasp!) it has a long cord, both of which are not shown in the product description page. The receiver must be plugged into the USB port of a computer. Instead of freeing up more space on my desktop, now I have a receiver, a long cord, and a "cordless optical trackman" that's twice as big as the traditional mouse. GO FIGURE.

No matter. If the trackman does its job and spares my index finger from pressing down a zillion times a day, then the bulkiness and "cordless" cord are just small tradeoffs. However the movement of the trackman is not as precise as I'd expected. The moment I let go of the click button, the selection moves slightly and there goes my eye-straining effort of aligning just the right amount of space. I ended up using my old mouse so as to avoid defining the precise dimension of objects by entering numbers.
