I often give presentations and it's quite a treat to be able to stand near the screen talking about some point and be able to flip between slides as needed. Range from mouse to receiver sometimes is easily 9 feet. No problem. I also have a Remotepoint mouse, but I've never used it 'cause I don't feel the need to change mice, or the benefit of carrying two. My only complaint, and I can barely call it that, is I'd like longer battery life.
