Get it now. You might need it.
I was fortunate enough to grab this app just before having eye surgery which left me supersensitive to light for many days and unable to read; even the iPad screen was like looking at the sun. I was able to link overdrive to my Carnegie Library of Pittsburgh account and borrow audiobooks. (If you belong to more than one library, you can link them all.) With nothing else to do, lying in a dim room and listening to some old favorite short stories as well as some new books I really wanted to read was awesome --- like having someone reading to you and even if you drifted off to sleep they would still be reading when you awake. My advice: get overdrive, link it to your library, and add a book or two to your bookshelf. That way if you ever need it whether due to illness or a long flight or car trip, it will be ready for you. I love its ease, functionality, and reliablity, and its free! And remember to make a donation to your public library so that benefits like this cant continue.
