> I think it's unclear how scalable and replicable The Magazine's success is (or even how successful it is).

At the very least, any publications that follow in The Magazine's footsteps stand a far better chance of success than the current lot of broken-by-design Newsstand apps. Every time I see a magazine app whose thumbnail is the cover from their print edition which is too small to even read it's obvious they haven't thought much about what it means to make a publication for a smartphone. "Exporting to app" from InDesign just isn't going to cut it. Marco's app is among the first that seems to have actually taken design of a mobile publication seriously.
