I guess I'll wait to see what TV+ brings later before declaring yesterday's Apple event a total yawner, but it did remind me to check out Flipster and Browzine again before spending any time and money on News+. What are Flipster and Browzine, you ask? They're digital magazine and journal platforms that you might want to check before you shell out money to Apple, since you may already be able to access the content you want for free.
Flipster is available to me through my local public library, and offers only 51 titles, though what your library offers likely differs. You can browse all potentially-available titles on the EBSCO Flipster site.
Browzine is more oriented towards scholarly literature, and is thus likely offered through your local college or university. I couldn't find a list of individual titles, but here's a list of the publishers they cover.
Both offer apps for your iOS (and Android) devices, and both work quite nicely.
Oh, and for newspapers, poke around your public library web page for PressReader.
Here's a list of the titles available in Canada for News+.
UPDATE: Lifehacker has a similar post, and theirs clued me in to something called RBdigital Magazines, which was new to me. My Public Library has it, and it appears to offer 190 titles, so depending on what they all are, possibly my best bet. Will be exploring...
