Kindle for iPad supposedly support magazines, but I haven't started using it yet. I'm already reading magazines on my iPad thanks to the iPad edition being available. Yet, some magazines aren't available on Apple's platform. I guess this is where Zinio comes in handy, but it's another app. How many of you are using multiple apps to read your magazines? Is Zinio for iPad worth it? If the same magazines was available for both the iPad and Zinio, which one will you go with?
