All-in-one devices often overpromise and underdeliver, but simple combinations like this one make traveling lighter and presentations smoother. With no tethering wires, these small hand-held devices flip PowerPoint screens and emphasize on-screen points with a laser light, yards away from your computer. When finished presenting, go back to your hotel room and use the mouse, sans cord, as you normally would.


Logitech Cordless Presenter, $200
Pros:
Compact and cool modern design. Converts from cordless optical mouse to Bluetooth-enabled pre-senter — with the standard Bluetooth range of 30 feet — with a simple flip of a switch. Includes a USB receiver.
Cons: Cutting-edge technology and hip design come at a higher price.
Bottom Line: If you have or plan to get Bluetooth, this is the one. If not, why pay extra for the technology?

RemotePoint RF, by Interlink, $249
Pros:
Works up to 100 feet away and can handle eight different presentations all on one frequency (traveling through walls, for example, at a conference center).
Cons: Could use a design update from the boxy old TV-remote look. Luckily, a smaller version with the same features is expected to hit the market within six months.
Bottom Line: Although pricey, it comes with tons of features and biggest remote range.

Phaser, by IOGEAR, $60
Pros:

Cons: Only works with PCs; sorry, Mac users.
Bottom Line: Not as many bells and whistles, but basics are all there at a bargain price.
