Hi all. I was wondering if any of you knew of a nice Bluetooth clicker/remote-control for giving presentations? (Obviously, the pinnacle of clicker perfection would be the one Steve Jobs uses for his keynotes, but apparently these are custom-built for him.) If I had a Bluetooth phone I'd use that with Salling Clicker, but unfortunately I don't have one. The only clickers I can find are Keyspan's RF clickers which all use a USB dongle, which is fine, I'd just prefer to make use of my PowerBook's built-in BT. Any suggestions?
