For a while I had a Sweep [0] keyboard that I'd carry with me and use everywhere, even in trains when travelling. It was small enough to be placed on my laptop, one half to each side of the trackpad. I use a ThinkPad with Linux for personal use and a MacBook Air for my job, I used the Sweep with both. While I prefer trackpad to mouse, I imagine mouse enjoyers would probably do something similar.
