The Kensington Presentairtm is one of the best (and best looking) laser pointers out there, incorporating Bluetooth control for the screen as well as a stylus to use for annotations or just taking notes during before or after your presentation or lecture. It lets you actively control your Powerpoint or Keynote presentations, including flow control as well as blanking the screen. It is rechargeable via USB and comes in a solid case to protect it when not in use. Don't just take our word for it, though, here is what CIO magazine thinks about it. And, oh, did we mention it looks good?
