As the article notes, don't try and buy one of those right now. However, the novel thing about that mouse is the gel pad that guides the cursor. The shape of that mouse is already on the market, there's a design that's known variously as Wera Mouse, which is sold as an ergonomic aid, but the same device is also sold as Poker Mouse, supposedly superior for online poker, if that's your thing. I've had it in mind to give it a try, because I rather like the idea of not having to be fixed to the desk surface, and it's available as wired or wireless. Interestingly, the poker mouse has a ball, a pad version without the ball, was listed for sale at one time, but not currently. There have been previous efforts at a similar design, I remember nearly ten years ago one being sold as "rocket mouse".
