You basically just convinced me that I should be training my left hand to use my mouse. In all cases except precision work (eg graphic design) it should be doable.
Side note, but if you actually do graphic design, get a digitizer/gtaphic pen tablet, it is simply "another world" when compared to mouse, nowadays even an el-cheapo one ( i.e. something in the 40-60 US$ range)is good enough for non-professional use.
