I've recently purchased one of these and although I haven't spent much time using it just yet, I love it! It's the world's smallest digital portable photo printer, which can connect to pretty much any bluetooth device capable of sending pictures. It comes with a rechargabel lithium battery, and doesn't require any ink! It uses Zink paper - ZINK stands for Zero Ink - a new and simpler approach to printing where high quality, colourful, durable and affordable prints are created -- all without a drop of ink. The ZINK Technology encompasses both the ZINK Paper and the intelligence embedded in every ZINK-enabled device.

The patented ZINK Paper is an advanced composite material with embedded yellow, magenta and cyan dye crystals, activated with 200 million heat pulses, in 30 seconds, in a single pass. With 100 billion crystals in a 2 x 3 inch print, the paper is 100-percent inkless. A ZINK-enabled printer uses heat to activate and colourize these crystals.

Here's a few examples of the fun to be had with the PoGo, I'll post my own work when I get around to it :)
