I agree, beside a few exceptions (photoshop/illustrator, 3d modeling/animation) I've never found a mouse to bring any benefits in terms of speed or even ergonomics. ps: that said, people who try to think about mouse interactions patterns can do wonders, Alias Wavefront labs used to make their software extremely fast with mostly mouse and a few keyboard modifiers. Briliant people.
