Wireless Presenter w/ Cursor Control

In my job, I do a large amount of presentations to the public and to my Team Members. I generally run back and forth to the screen to emphasize important points. It is a lot to do after walking the compound all day and smiling with all the customers. So, I finally remembered to check on a presentation pointer when I was in Staples yesterday. I found a great one by Targus. It's a combination remote control mouse and laser pointer. With this pointer you can control cursor movement anywhere within 50 feet of its receiver and project a red laser pointer beam. How nifty is that?
