It is good to hear (read) comments about other brand components. I won a MonopolySoft wireless keyboard and mouse last Mac Expo, but haven't had occasion to install it yet. This posting makes me pause and give serious consideration whether or not I want to experiment with something from MS's factory of dubious peripherals. It is beginning to look like I should sell/give away the MS product and buy an Apple set if I decide to go wireless. I wonder if there are any unsuspecting PC users that I could interest in buying the unused MS set?
