I’m not a big fan of people using a wireless remote during PowerPoint presentations because the sheer act of holding a remote tends to stifle the natural hand motion of speakers. The fewer natural gestures, the more stilted and less natural any speaker appears to be.
However, if you are going to use a remote control to advance your PowerPoint slides, I recommend that you use one that is shaped like a normal sized computer mouse that can sit on a table near you during the presentation. At first blush, the thin, credit card sized remotes would appear to be superior to a remote as big as a mouse. But the credit card sized remotes have to be held in your hand anytime you advance a slide (and they have a pesky habit of staying in your hand throughout the presentation).
