| This is my second Logitech trackball. The first gave me four years of heavy use before the ball became sluggish and the left button, the main button, got cranky, wouldn't click predictably. Well, everything with moving parts finally wears out. (The regular cleaning this device requires, like the ball in a conventional mouse, no longer responded.) My first use of the new one was like pulling out in a new Mercedes. The ball responds to the slightest touch -- a most delicate resistance provides precise accuracy of movement. The buttons on the new one have something the old version didn't have, positive tactile clicks. I don't understand those who have trouble training the thumb. It is, after all, the second most agile digit on the hand. Thirty minutes and you're proficient with the ball. A slight flick of the thumb sends the pointer clear across the screen. Another complaint I can't understand concerns delicate pointer positioning with the roller ball. The thumb can provide much more precise movement than the hand holding a conventional mouse. I often work with graphics, following irregular lines. The conventional mouse gave me a lot of trouble. Not this one. I can trace the most delicate pattern with ease. As for zeroing in on radio buttons -- Good grief! Nothing to it.... Anyone who gives this mouse a try will love it. You'll not miss running off the mouse pad, having to pick the mouse up and "return to start" to get back on course. All the wrist movement will be a thing of the past. You won't have to push papers out of the way now and then to maintain the airfield a regular mouse demands. Just yesterday I worked on a friend's computer and was cussing his old-timey mouse, wondering why users put up with them. I secure my TrackMan to the desk with a little patch of Velcro. If I don't like the position I can change it. Once set, your hand falls on it in precisely the same way every time. As for that wheel ... well, I can scroll with scroll bars better, and I don't need the Internet menu that is provided as the default click. (It can be programmed to do other things, so you might find a use for it.) It does have a function for me -- a nice little ridge that seperates left and right buttons. Someone below reminds us that all other mouse software (even Logitech) must be removed before installing the Logitech software, and that should be done. Do it through the formal uninstall process (My Computer, Control Panel, Add/Remove Programs, Restart). And remember, since you won't have a mouse during the short installation process, that Control-Escape brings up the Start Menu, arrow keys move you around in it. The Enter key will activate default buttons and Alt-(letter) the others. We only use two devices to operate these incredible machines -- keyboard and mouse. If you take my advice and get this mouse, you'll be at home with it in no time, wishing you'd made the change sooner. As for keyboards, I had the Microsoft Natural Keyboard a year before I gave it a try. Voila, another one-hour period of adjustment. I was right at home with it in a few days. Now I HATE the conventional one. The above from a guy that uses a computer and a variety of fairly sophisticated programs all day every day. |
