As a long time reader of the paper edition, I have looked forward to this app for some time. Access to individual articles is excellent and exploits the abilities of the iPad perfectly. The option to scroll through thumbnails of each article with a horizontal swipe is particularly well done. Integrated videos are a great enhancement as are interactive graphics. Linkage to web-only articles is an enhancement that goes beyond the material available in the print edition. Having made the switch I would never want to read the magazine any other way. Some reviewers have questioned the cost versus the print edition (about 75% more than print): this is a legitimate issue, and was particularly so when digital meant access to downloadable PDFs that exactly reproduced the paper edition. For me, the new iPad edition offers me significantly more than the print edition and this partly justifies the price differential; as time passes and the number of monthly editions that are available for iPad increases, the value will be more compelling. The subscription cost gives access to the back catalogue, something that print subscribers do not enjoy. As of now digital subscribers can access back to July 2012 in iPad format and as far back as 1993 via PDF: this has been an excellent resource for my kids. I have an older iPad and do not see the quality degradation that has been mentioned by owners of retina iPads. Hopefully an update will address that issue.
