Great article Rob.
Even though I doubt I will ever buy that particular Microsoft keyboard combination, I still enjoyed the piece. I enjoyed it because I have been using Microsoft mice and trackballs for about six years now. The software is not the greatest perhaps (but hey, its Microsoft, what did you expect?) but I have found them to be rugged and reliable..
I Infact, the mouse I am using now I have been using since 2001.... six years and still going strong! I see no need to buy another since this one works as good as the day I bought it.
