My current pointer had been reduced to only a slide changer. This finally allows me to indicate on screens other than just projector screens, and over Skype presentations too. Also, a nice big indicator point that people can see easily. The flash drive built into the dongle is great too - your presentation can be handed over with your clicker USB. The only downside is that the pointer program needs to be loaded from the dongle - but still vastly easier than the usual problems transferring files.
