audio magazines as .pdf files - hifi+ specifically

Have any audiogoners converted to .pdf files your back issues of audio magazines?

I wish publishers of audio mags should offer .pdfs delivery for subscriptions and a trade-in/replace with .pdf service for back issues so we can all make more space on the shelves for vinyl.

The dvd set the new yorker put out is a great model.

Also, does anyone have any experience with the hifi+ digital download system (newsstand.com)? I think that is the only rag worth the paper it is printed on, but I still love the idea of eliminating the paper. I am hesitant to be buying files that are dependent on newsstand.com software that will likely be obsolete and unsupported soon. Any thoughts on them?
