I use one when running my iTandCoffee classes, to project my iPad's screen up onto a big TV screen.
Just last night we rented the movie 'Guardians of the Galaxy' using our Apple TV, and watched that together on our family room TV.
But just before we did that, I showed my family a video that I had seen on Facebook, that shows how to really, really easily put a quilt cover onto your quilt.
From my iPhone, I 'airplayed' the Facebook video (via our Wi-Fi network) to the TV screen for us all to watch.
(Check out that amazing video here! I can't believe I had never seen this before!)
Are you wondering if the Apple TV has a place in your home? For me, the relatively low price tag of only $109 (sometimes less on sale) made that decision easy. Here are a couple of articles that might help you decide for yourself.
