Could this better sound editing?

How many of us are always trying to find the perfect way to work? When editing sound, the traditional mouse is the first peripheral to go due to bad ergonomics. Most editors work with trackballs, however even this tends to have slight problems depending on your desk/ chair height combination. Apple today released the Magic Trackpad. Could this be our next favorite editing tool? With only a quick look at it and no actual physical testing, I am unsure of how accurate cursor movements will be. If they are acurate, than this may  be a handy device to have.
