I've ran the latest firmware update (0.47) on 1 Elonex 511EB and compared it to a second without the update. The system font is smaller in size as are the headers and footers on the page when displaying a Epub. This gives you more reading room. The main display font of the book when running an Epub is actually slightly larger. This, my wife and I agree does make it a crisper font to read. I'd say in font size terms it may have gone up 0.5 or 1 point. The little numbers down the side of the page now tend to block a couple of letters rather than a word once they hit 3 digits. Happy so far with this update, not really tried out any of the other know changes or found any new.
