Here's my Ploopy Adept unbox and initial review.
I wished I could CHORD buttons like I do with the Kensington slimblade & expert. I need cut/paste as well as ENTER, forward/back browser, right/left clicks, and scroll wheel. The buttons are also quite cramped for my dominant hand. The reach around the ball to dragscroll or otherwise reach the mid-top buttons wrecks this trackball for me as a daily user. I enjoy the smoothness of the ball and switches so much more than on any of my other trackballs though - so this is a partly love, partly hate trackball. It would be so easy for the makers to enlargen this trackball and add a couple more buttons or a scroll wheel. Such a trackball would be the absolute best of world. As it is, it is a very flawed trackball with a few world-class features.
