I headed over to Staples after the piece of crap mouse that came with my new Dell computer died. It was the cheapest mouse I have ever seen. It never worked anywhere near right, and it worked even worse after I beat on it repeatedly with my fist. Staples had the marble mouse on display, and its' unusual design and low price caught my eye. My first reaction was "this'll never work," but the more I played with it the more intrigued I became. So I bought it.

I've had it for about 2 weeks now, and I have to say it's pretty cool. I have a desktop recording studio, so desk space is very cramped. Invariably my regular mouse was slamming into another piece of equipment before the cursor had traveled far enough to do what I was trying to do - way annoying. That is obviously no problem with this device as it stays put in one place. On the downside, you have to relearn EVERY operation that you do with a mouse. Everything is done differently. On the upside, when you do relearn things, they are generally easier. I will agree with the reviewer who said that this device was way too fiddly/jerky for detail work. Things like opening up a drop-down box and choosing an option can tax your coordination (no twitching, please!). It certainly wouldn't be my first choice for computer graphics work, but then that's why I bought a Wacom tablet (although, to my surprise, I did find myself using the marble mouse in Photoshop the other day). The ergonomics certainly aren't perfect (even for those of us that DO have catchers mitts for hands). And frankly, I'm not sure that this device is a complete mouse-replacement either. I've been cheating and have been using the mouse that works, albeit in a very limited way, with my Wacom tablet occasionally as well.

Overall, an interesting addition to your pointing device arsenal that is worth a look.

UPDATE: I have owned this pointing device for 5 years now, and I use it for EVERYTHING, even 2d and 3d modeling and animation. It's only weakness is the lack of a scroll wheel. I am sure they coulda put one somewhere.
