Thought I would pass on some info about these trac

Summary: I have been using Adesso ProCat 4 button touch-pad for about 26 years. I have the 4 button one and it has a Serial connection! If they ever stop putting a Serial connection on mother boards, I'm in trouble. Try the 2 button one 1st, then get you a 4 button with the larger pad area. It takes a little getting use too, but you can adjust the length of the mouse travel, the buttons and such. Once you get the hang of it, you'll never go back to a mouse- ever!
Summary: Obviously you are not getting an Apple touch pad for $30, so expectations should be checked. However, the touch pad is more sensitive than other Adesso pads on keyboards I have used and the buttons have a great feel to them. I just wish they were spaced a little farther away from the pad surface for a more ergonomic feel.
Pros: Good sensitivity, up/down scroll works well, button click feel is excellent- not too hard or soft, pad responds well to tap-click on the pad and is not overly sensitive to accidental taps.
Cons: Device is thicker than it needs to be, the touch pad feels slightly grainy, the buttons are too close to the touch pad and can make hands cramp over time, no side/side scrolling.
Summary: Purchased this to replace a very old touchpad. New is smaller and more features. Only real downside is it is much lighter and whole touchpad tends to move while using it. I don't care for the standard mouse due to the amount of area they need to operate, therefore I use touchpads or trackballs. A plus for this is no moving parts to worry about to clean. This touchpad has more features then any trackball I've seen. Remembering to use all of it's features will take time.
Summary: This is my second Glidepoint touch pad and its just as nice as the first. For constant computer users the touch pad technology is a must, it provides much hand, finger and wrist relief. Navigating the device does take a little while but the learning curve is small and worthwhile. The pad is very small and light ( a small piece of Velcro on the bottom works nicely as an anchor).
Summary: I bought this with the intent of trying to give my 'mouse hand' a break. The shape of the mouse leaves my fingers in an unnatural angle after a while and my arthritis is certainly letting me know. I bought this pad as an attemps to make it better... and it works well. It offers me flexibility of movement and still performs all the actions of a regular mouse (plus a few extras)!
Summary: I returned the Item because the buttons on the touch pad were dead and the install disk with the 'drivers' on it was Blank - Pad still did not work (dead buttons) even after I downloaded the drivers from adesso's web site - I've used Cirque touch pads for years and have never had any problems - I will NEVER buy Adesso again as I have had to return every Adesso product I've tired, the touch pad was thier last chance and they still blew it - should have known better and...
Summary: This is the only computer appliance I've had and still use exclusively for over 9 years. The thing won't die or falter. It has a sequential connection which, as I upgraded my computer, I had to apply a ps2 interface cable. I use the mouse software that comes with the operating system. I bought it for games on my home computer and then bought another one for work---network engineering. I've been through win 95, 98, 4.x, 2000, and xp and will use it for 7.
