Query: State Of The Art For Ordinary Human Beings!

As someone who has run through a number of "inexpensive" devices that quickly get dirty, wear out, and cause frustration and agitation when they start to act up on me, as they always seem to do at the worst possible moment, I sure have enjoyed the run of good luck I have had with this new faster and more convenient mouse so far. Believe me, I am no technophile, but I do use both the keyboard and mouse a great deal in either writing or surfing the net. As a consequence, I have loved the Intellimouse in the short time I have had it. Since it operates on an optical basis, it is faster and much more flexible and convenient to use than the traditional mouse products I am accustomed to using. Take it from a normal human being; this is a great product, one that should last longer and be much more pleasant and dependable to use than the old types! Enjoy!
