Even if you don’t give presentations all that often, for $6, it can’t hurt to keep this well-designed PowerPoint remote tucked away in your bag. Powered by a single AAA battery, the remote speaks to any Mac, PC, or Android device via a tiny wireless USB dongle from up to 100 meters away. Most importantly though, it includes a built-in laser pointer, so you can use it to play with your cat even when you aren’t giving TED talks.
