Ergonomic, Durable, Easy Connectivity, Versatile, Fast Connection
My high school foreign languages teacher brought one of these in from home to use with his classroom's LCD projector, and we liked it so much that we immediately bought two more and have placed in next year's budget one of these for each teacher. They are fast, convenient, and allow the teacher to exercise good classroom management techniques while using their on-screen presentations. (ie, they are now untethered from the computer keyboard and able to walk freely around the room while presenting!). Worth their weight in gold, and have paid for themselves many times over in recouped instructional time and increased effectiveness (can you say "productivity-booster"?)in the short time we have had ours!
If you are a school or business presenter with an LCD projector and don't have one of these, what are you waiting for???
