Zinio for those that don't know is a magazine app which allows you to subscribe to and read tons of magazines. I use Zinio on my PC and on my iPad but would love to use it on the Playbook. I wrote to Zinio asking about a Zinio app for the Playbook and their support group wrote back to say that their QA department is putting the finishing touches on their Playbook app and it should launch in early summer.
