With the state of air travel the way it is today, leaving the laptop behind almost seems like a good idea. If you do, a new air mouse can still make sure your most important PowerPoint tool still makes the flight. Gryation's newly released Gyrotransport (available now for about $200) works just like a traditional mouse, but it can do double duty as a wireless presentation controller. With the Gyration, you use a variety hand "swipes" and other motions to switch slides or activate various features during a presentation. The super-compact device also features 1-GB of built-in flash memory in a dongle that detaches from the air mouse and plugs into any USB port. The air mouse can then operate from up to 100 feet away using 2.4-GHz RF technology, so you don't even need a line of sight to the dongle. It's like being a puppeteer without the strings. — Peter Suciu
