about reading ebooks on a Tablet PC using a two column format. They are said to describe how to do it with the yBook and Bookshelf ebook readers. Might be useful so some, but I kind of enjoy on a full screen reading in one single page so I'm not sure what I think. The difference, I suppose, is that on a Tablet PC you are probably up closer to the screen, so it would be more like the paper book reading experience. Worth checking out if you read ebooks on a Tablet PC.
