I checked www.zinio.com about this, and all I can find is a page that says it is coming soon to the Android market, and that we should check with our mobile carriers for details. I am not sure why the carrier should matter when it comes to apps.
So, will the Zinio magazine app will be available for the Motorola Xoom at some point? Having that app would turn the Xoom into the perfect tablet. Right now it is close to perfect, but not quite there yet.
I am happy you are enjoying your Motorola Xoom. At this time the Zinio app is not available for this particular tablet but you can go to Android.com to review all current applications. I have also listed a link below to ask more questions about specific applications for your Xoom. This community of users, together with a team of Android Guides who post periodically, enjoy helping each other figure out the best to use the applications from the Android market.
