I am looking for a way to display photos, videos, Powerpoint, etc. from my old Apple PowerBook on a TV. (My new Apple MacBook comes with a remote that seems to work well.)
UPDATE: Rockin’ tells me this device works with Powerpoint.

Keith is happy with the SmartDisk product which works plug-and-play with his PowerBook.

I have had good success with the Keyspan iTunes remote — designed for use with iTunes but works with other applications like PowerPoint. http://www.keyspan.com/products/usb/urm15t/homepage.spml
