Sometimes, when I'm wandering the cold, dark streets in search of some food or another victim, I spot an obvious business opportunity - taking the photo of a happy group of revellers, perhaps, or documenting a road traffic incident. Of course, I never actually get round to emailing those photos off, never mind printing them and posting them via snail "are we nearly there yet?" mail. What I need, I hear you grumble, is Fujifilm's Pivi MP-300, a portable photo printer that not only fits into your (somewhat large) pocket but can connect via infrared and PictBridge USB to compatible digital cameras and cellphones to produce business card-sized snaps.
Okay, so it's a mystery why they chose infrared and not Bluetooth - perhaps they're planning a special edition "Beam it in Blue" for next Christmas or something - but I can see this being a useful little gadget. Sadly it's Japan-only for now, and costs around $130.
