TBH, I think 5$/issue is a bit steep. In Canada I currently pay 40$/yr for my print subscription and I know that an American Print subscription is 20$/yr, so the price difference is pretty substantial. I will be keeping my print subscription until prices are more reasonable.
I'd buy it if I'm getting on a plane. Other than that, I just read their website.
But if I can get the info I'm looking for from their free no-storage website (and 30 seconds later bounce to another website, as we web folks are wont to do), it's really hard for me to get motivated to remember to go buy a $4.99 1 GB (500 MB on my iPad, 500 MB on my Mac where iTunes lives) app every month.
How can they successfully compete with themselves? And yet they can't shut off their free website and become utterly irrelevant.
