The Cost and Subscription Options
I'm an occasional user that only needs some of the premium features in Reader once in a while. An example would be adding or removing pages. $13.49 per month is absolute robbery. Instead, I use free programs when needed. Why not offer reasonable pricing plans, with annual payment options that non-commercial users can afford. Adobe thinking seems to be they'd rather have 100% of $0, rather than price it reasonably and add millions of new paying subscribers. Adobe is the best product; why not price it cheap and drive the copycats out of the market.
