Thanks Cajun, but unless there is something there that I'm not seeing those are only the old models, the "M03-00045, M03-00043, M03-00041 and M03-00035. There is nothing there I can see that describes the new intellimouse models that are due to be released on April 1, the "M03-00059 Immersion" and the "M03-00061 Night Vision".
What I am trying to find out is what is different/new/improved about the new 59 and 61 models as opposed to the old 35, 41, 43 and 45 models?
