Ran across the Impactica Showmate, a $249 item (gadget?) that allows you to present Powerpoint presentations wirelessly via Bluetooth directly from a Blackberry - no wires, no laptop. Most of my presentations have a demo part that requires a laptop and I always have a copy on USB key just in case, but still, this seems interesting. One more way to get some additional mileage out of the phone. Cost seems way high from a consumer perspective, at $49 I'd buy it, probably not at $249!
