On my end I'm actually looking for a reliable and easy way to cut down the use of printers at work with an eInk based alternatives. If only there was Letter/A4 sized color-eInk reader that was fast, could take a multitude of formats easily (PDF, LaTeX, you name it) and have it show up as a virtual printer (preferably with authentication so that not everyone can send a print job to it) on all common OS, that'd be great. You just send your documents to it prior a meeting, your scribble some notes and save them to a storage system of your choice for archival.
