The format does not get distorted. Before the 2.5 update, you were restricted to viewing the pdf in a landscape view at page width. So if you have an A4 sized doc, it would take about 2-2.5 'nexts' to get through a page. It was readable and I read a number of journal articles and programming books that way, but it was a less than ideal experience. Post-2.5 allows you to zoom pdfs and pan.
