The Exact Editions interface is one of the best online magazine interfaces I’ve seen, providing the ability to zoom each page and navigate through the document using embedded hyperlinks, spread thumbnails, and navigation buttons on the interface. In my opinion, the EE interface is even better than a high quality, fully bookmarked and linked PDF document. The page scans are relatively high resolution and hold up well to magnification, and the reading experience is as good as, if not better than, the experience of reading traditional paper magazines.
But you must read the whole thing. Alan and Michael think that digital magazines have lesser ecological impact than print magazines, and bikes are a low impact way of travelling. That must be right.
