A joint storefront from top publishers to sell tablet magazines, Next Issue, will launch on Android first and not the iPad, its CEO Morgan Guenther said today. While there weren't any technical obstacles to an iPad version of the store, Next Issue said it would go with an Android version first since it was a "very important tablet platform" and also important on phones. Support for Apple would come in time, he told AllThingsD, but only the Android version would be ready for the early 2011 launch.
