I'm really looking forward to a good electronic replacement for paper.
After a long search for an e-reader that can handle academic papers, I came up empty handed. There just isn't a good solution right now since most devices have a screen that's too small and ebook conversion isn't a good workflow. Additionally, my field has lots of colorful figures that are hit or miss when converted to greyscale. The readers that are big enough also seem to get pretty mixed reviews.
What I really need is a dumb A4 sized e-ink PDF reader. That way I can stop printing out every article I want to read.
I'm sure that someone could make a killing on this product if it was at the right price point since most of my friends have a similar need. I was kind of surprised that nothing exists yet.
