I'm in a library, using a Macintosh. I've got nothing against Macs, but my fingers keep reaching for the right button and the scroll wheel as a matter of habit. Neither of which, of course, exists on this Mac mouse (which is more reminiscent of a transparent bar of soap than anything I've come to identify as a mouse).
And there's an icon jumping up and down on the bottom of the screen, inviting me to mount the MDrive, which is really annoying. I can live without a scroll wheel, I can live without a right button, I can even live with the fact that the <Home> and <End> keys apparently have no function whatsoever. But that smegging scroll jumping up and down every two seconds is really getting on my nerves.
The interface looks nice, though.
