Hi -
My name is Davis Fields, I'm a product manager at Next Issue (so, obviously biased here), but, wanted to note that you can install the application on the Galaxy Tab 10.1 directly from the Samsung Apps store on the device. We're doing some work right now on an updated version to come out in a couple weeks that adds some new features and makes the entire application look better on the 10" Android Tablets (we launched our preview release on the 7" Galaxy Tab).
At any rate, you can follow us at nextissue.com and on twitter @nextissue where we'll be posting updates as we grow. We're at very early stages right now and have plenty of cool stuff on the way, happy to have you join us here at the start.
