Jim Dalrymple, the veteran Apple journalist behind The Loop, is launching a new magazine for iOS devices today. Rather than simply being an iOS version of the existing site, the magazine version of The Loop is a separate publication hosting longer form writing from a variety of contributors and perspectives. As Dalrymple notes in his welcome message:For many years people have been asking me why I didn't release an app for the iPhone and iPad. The answer was simple: I couldn't find anything that added value to what I did on The Loop. I wanted something more than a side-scrolling news app that basically imitated what I'd already linked to or written on the Web site.
