AirDrop is a feature that lets Macs and iOS devices share files
wirelessly with a minimum of fuss. AirDrop is extremely cool and useful, but is one of those features most people don't know about. Not because it is hard to use (it isn't) but because most people don't think to look for it. Most of the time when we want to share a photo with someone, we just send it to them in a text message. Which is easy enough, but when that someone is standing right beside you, it is even easier to simply use AirDrop.
AirDrop isn't just for photos, of course. You can use it to transfer almost anything that you can share. For example, you can AirDrop a website from your iPad to your friend's phone, which is great if they want to bookmark to read later. Or what about a grocery list? You can Airdrop text from Notes to someone else's iPad or iPhone. You can AirDrop anything from a playlist to a location you've pinned in Apple Maps. Want to share your contact information? AirDrop it.
