i'm a developer and i don't like mice, but i <i>love</i> my mac's touch pad. two finger horizontal and vertical scrolling is <i>awesome</i> for reading code quickly, and then getting back to typing. i prefer the continuous movement provided by the touchpad over keyboard shortcuts (er, long cuts!)<p>(i've made my own foot pedal for fun, but i don't suffer from wrist problems normally. i use emacs key bindings with eclipse)
