The Califone LP2 Laser Presenter And Wireless Mouse is a laser pointer with a 650 foot range and a wireless mouse that's both Macintosh and PC compatible.
It's got page up and page down buttons so you can use it to move through PowerPoint, Word and Excel files.
At first it looks like a one piece unit, but to use it as a wireless mouse you simply separate the USB mouse receiver from the pointer and plug it into a Mac or PC. You can then control your presentation from as far away as 50 feet from the computer.
