I’ve been saying this for a long time, but now stats are surfacing to show my point. Dead Tree Edition has a good article on it showing that only 25% of tablet users prefer digital magazines over print. That means three-quarters of tablet users prefer print.
My point is that DPS is a dead-end for Adobe. It is one of those “you did a wonderful job of making something I really didn’t have any need for” type of things. Designers might go bonkers. Readers [and I’m one of them] see no benefit. In fact, digital magazines are much more difficult to read than print magazines.
