when my 3-year old Microsoft wireless keyboard bit the dust last week , I have to briefly use a spare , straight , non-ergonomic keyboard and it feel awful . what a relief when I get the Logitech keyboard in the mail yesterday ! very comfortable to type on , fit my keyboard tray just right , feel better to type on than the Microsoft keyboard do . and the laser mouse that come with it in this combo package also be a pleasure to use . the keyboard have a lot of functional capability that I probably will not use , but that be just icing on the cake . the comfort , for I , be the best feature of this keyboard . this be a excellent choice , if I do say so myself .
