I had a Sony reader and then got the IPad for Christmas but not thrilled about the size for long term reading. DH surprised me with KF last night but each of the Overdrive apps that come up in a search say "unavailable". Is this something I am going to have to "side load"? Never even heard of that until the last 10 minutes. I'm half tempted to take the Fire back if it is going to be that much trouble. (I'm older and not too techno savvy, just want it to work out of the box

)
