I just switched from paper to digital when I renewed my subscription to
Linux Journal.
Of course, unfortunately, it's published as PDF. I'm not very happy with the format at all, though at least the text is laid out in narrow columns in print, so it's not to hard to read. But going from column to column and page to page is confusing and the TOC doesn't seem to work very well. I've asked them to also produce an epub version, but I've received no response so far.
Is anyone reading a magazine on their reader, especially a 6" reader, and enjoying it?
