One of my favorite magazine, TrailRunner, now has a digital edition. Unlike The Atlantic or Foreign Affairs that simply offers their content online, this is a real tree-less version of the pulp version with flipping pages and everything using RealRead.
It's an interesting idea. It may simplify content management system (CMS) requirements, implementation and management costs while at the same time providing a "natural" (traditional or to the techies, Luddite) experience.
Interesting. Although I'll keep my hard copy, I spend too much time in front of the computer as it is, it could be a valuable resource for making content accessible to developing or poor regions around the world (the former referring of course to non-US locales while the latter may refer to US domestic locales). Make this technology available through projects like the Iraqi Virtual Science Library, usable with $100 Laptops, and you've made content more accessible.
