Tom is looking to get an iPhone or an iPad for work. He's never had one. Leo says to get an iPhone first. Get used to it. Then if he needs an iPad, he can go from there. He will also need an AppleTV if he wants to push the screen from the iPhone to the TV. It's called AirPlay. Plus, modern TVs can cast directly from the iPhone or iPad without an Apple TV because Apple TV is built-in. The Vizio Smartcast is a good one.
