Seems rather antiquated to subscribe to a magazine [paper version] nowadays. The only times that I have actually read a paper magazine is when my internet connection does not work. Even then I would rather read a book than a magazine.
I would have to subscribe to so many to get the different point of views. Personally I use RSS readers such as Google reader to browse through the content I want.
Taking a step back, I can see the value on a paper subscription to The New Yorker because of the kind of product and experience that they provide.
The New Yorker has longer shelf-life and engaging content wrapped around a lazy Saturday morning laying in bed with a hot cup of chocolate and freshly toasted new york bagel with a delicious layer of cream cheese on top.
