Overall I like the interactive interface and makes great use of the retina display. This is so much better that the R&T app for which I have since cancelled my subscription.
The negative I do have is that it can be viewed in landscape orientation only. Perhaps its something you get used to but I like the option of viewing in landscape or portrait..... and, if I could only pick one, I would prefer portrait for reading magazines.
