This is may be the last three-button mouse. Not a scroll-wheel mouse, but a mouse with three real buttons just as real Linux mice are supposed to have.

The ball doesn't fur up, because it doesn't have one. The battery doesn't die at an inconvenient moment, because it doesn't have one of them either. It doesn't paste your text in the wrong place when you accidently move the scroll-wheel as you press it, as it doesn't have a wheel.

I got it at Amazon for £14.95. I also got a spare, because there might never be another one. This may be the last three-button mouse.
