Way cool.

And there’s more on the site. Really interesting stuff.

Disappointing.

That’s what I call the Kensington Expert Mouse trackball.

It’s my own fault, of course. I bought it sight-unseen. That is, I’d seen the site and thought that it couldn’t possibly be that big.

Well, big it is. Huge in fact. I was hoping to be able to use it portably, for the laptop among other things. Not This Little Black Duck.

4-5 inches long by 4 inches wide, is freaking enormous by mouse standards, not to mention trackball standards.

I was finding the Logitech trackball a bit big, but the Kensington one makes my current trackball look positively tiny. Side-by-side, the Logitech one is half the size and half the weight. It’s also got a smoother ride on the ball, and while the Kensington one has a natty scroll wheel (around the ball), it’s not that big a deal.

I think I’m going to stick the kensington one on eBay as soon as I get home.

Note to self: don’t buy sight unseen. Unless it’s Apple stuff
