For years i was a print subscriber, always enjoying my weekly science fix. The only downside (besides the inevitable cost) was the overhead in the ever-growing stockpile of printed matter i had to get through. I took a crack at using the Zinio version (the print version delivered as what is likely a PDF), but even on the iPad the reading experience was awkward, and on my mobile it was a pain. Besides sidestepping Apples complex and poorly-managed subscription system, this app gives you a mobile-optimised view that isnt crap (its different than the print version, but you quickly get used to it), with hyperlinked content... and all at close to half the price of either print or Zinio. Plus, i can take as long as i want to work through my backlog of partially-read issues :P
