|If you double click on the kindle fire screen then the page zooms in and the text is larger. It is still not that large, but it is readable. You have to double click the page again before you can swipe to the next page, which is a bit of a pain, but it works.
There does not seem to be an offline version for the kindle fire though, which is a major drawback. The key advantage of a kindle is that you carry all of you books and magazines around with you in a small device. That's not much use if you need a live internet connection to read something.
