It's fair to say the odds were pretty stacked against a paper-based 2D printer making our Cool List. But the Little Printer isn't one of those monolithic paper-munchers of yore. A palm-sized, inkless thermal printer, it wirelessly chats to the cloud and sucks down daily 'deliveries' from your choice of sources. These are then printed out in neat receipt form for you to stick in your wallet, or scribble on during a screen break, creating a fun middle ground between the tactility of print and the immediacy of Twitter.
