I'm afraid the 'web' pretty much took over digital content long ago. Am I interested in digital books? Yes, very much so. But for 'magazines' or 'news'... I already have an endless supply of free (ad sponsored) resources on the 'web' I'm already comfortable with. Digital magazines and newspapers may just be a non-starter - I'm afraid they're way too late to the party, that ship has sailed.
I think you might be right there.
