If you're reading magazines on your iPad, there's a fairly good chance that you're using Zinio. Released today, version 2.0 of the Zinio app for iPad makes it easier to hand over those newsstand-like per-issue fees with in-app purchasing, while also adding a variety of free preview content, including access to current articles from thousands of top publications. The app's new Explore section hosts this new free content, which updates daily and includes stories from magazines like Esquire, Rolling Stone, and Elle. The new app also features significant performance boosts, like we saw with last month's Android update, in-magazine shopping, and advanced bookmarks. Another update in the coming months will bring social media capabilities, such as bookmark and article sharing. We'd still love to see lower per-issue and subscription rates, but we're happy to welcome free article content in the meantime. Jump past the break for a video overview, along with a sneak peek at those social media features with Zinio CEO Rich Maggiotto.
