Attention Newbies: All feature-rich magazines take time to download.
I expect that many of the reviews come from people who are new to iPad publishing. Generally, unless the publication is largely text only, and light on photography, video and audio (like The Economist), the file is going to take a while to download. The wait is usually worth it if you desire an interactive experience.
