I gave it a try for their free monthly deal which has two subscription plans and am quite happy with it. Each device works a little differently but regardless of the device, my one subscription appears on each device. Travelling without an internet connection only means selecting the magazine for download (Wifi only as I learned the hard way with my Ipad3 4G did not work--obviously worried about the data plan, I knew I had 5 GB so that wouldn't have been a problem but unfortunately there was no option to allow it). What I found great however, is that this makes the perfect app for the older ipad which makes the perfect bathroom reading device. With further software builds I would hope they will add the ability to bookmark where you left off as this will help when picking up a different device or moving to your desktop for reading.
So if you are in the market for a great way to revive your magazine reading without the exorbitant costs per magazine, Next Issue is definitely for you!
