Nope, I use it for 7-10 hour plane flights and it reads fine. I use DSReader for top-bottom reading, and when my eyes or hands get tired, switch to the Readmore app to read it like a book. You can change the font, font size, the background/text color, etc until its comfortable to read. I haven't found any homebrew that offers an auto-scroller, but otherwise this is the best handheld reader that I've used.
