I have been using a Cirque Power Cat for years and loved it. I bought the Easy Cat for two reasons: 1) the Power Cat does not plug directly into USB and I bought a new computer that has only USB, no DB9 connector, and 2) I'm unable to get the scrolling and zoom feature to work using the Power Cat on the new computer (running Windows XP Professional).The Easy Cat is very small, which I didn't like, but can live with. The USB cable comes out the right side which is rediculous. It should come out the top. The USB cable doesn't reach my computer, so I had to move things around to connect it. But, the clincher was that the touchpad doesn't work. I can't move the mouse cursor. The scrolling worked and the zoom worked, but not the mouse-move. The product is, therefore, useless.
