"Apple TV has proven to be a very useful gadget, both at home and at school. Airplay mirroring is its best feature. I am able to show whatever is on my iPad/iPhone screen and beam it up to a big-screen TV or a projector. I believe, at its relatively low price point of $100, any Apple fan should own one. In terms of the classroom, it can be a powerful tool for supporting your teaching. Teachers can benefit from being able to roam around the classroom and beam up multiple devices."
