Input:
My only problem is that in time the wheel has lost its "stiffness" and the detented turning of the wheel also has gone off; I called Microsoft and they sent a replacement; I have NO complaints and will continue to purchase this mouse...forever..even pack one with each Thinkpad case to be ready for travel.  Feel horrible without the Intellimouse optical.  Can't leave home without one.
Had one new one in reserve; just opened it and now I see they do not make this mouse any longer; boo...
trying to decide whether to order a new version or the logitech optical version. will keep monitoring this to get reader's opinions......This mouse suddenly stopped working; the pointer suddenly lost its ability to track. (That's another reason had so many in the past 3 years plus the wheel losing its stiffness and detented feel.
Logitech's got great products so this may be my opportunity to try one.
Depend on the feedback reviews here.
