I'll be honest here - I've never sat there with my phone and wished I could project its contents onto a handy flat surface, but I recognise that there's a few situations it might come in handy - a camping trip, or impromptu business meeting, perhaps.
Well, even if there's not much demand, Logitech Wireless has a solution regardless. It's the "Logic Bolt". It's got an inbult projector, which can throw a 64" image onto any white, flat, surface that you desire. It's also got GPS, a 3-megapixel camera and a touchscreen. Not exactly pretty though, is it?
