This tiny little printer is adorable. The idea is that you can print daily digests of RSS/Facebook/Twitter feeds and take them with you to read and then recycle. From the video, it looks like the software will be available to print from either your smartphone or your PC. It prints on thermal receipt paper, so no messy ink cartridges to refill.
I can think of another use for this – I’d love to set one up in my Grandma’s house so she can get daily digests of Facebook status updates from all her grandchildren. I could also see setting it up to just print all of her email (since she seems to have a hard time figuring out how to check it).
