I’ve always had a problem finding the best mouse/keyboard combo for my Mac Pro desktop setup. I’ve been a religious Logitech MX1000 user at work on my Windows box but wanted something to complement my Apple setup.
My Mac Pro came bundled with the Mighty Mouse and Apple wired keyboard and this was “OK” for the interim but much as I love the scroll ball on the mighty mouse, I found the lack of additional programmable buttons an annoyance. Granted I could squeeze the Mighty Mouse and program that to anything I wanted but it still meant I could only set it to forward or backward. I also like to set an additional button (normally the scroll button) to Exposé’s Show All Windows.
