It's like magic when it works. But in my experience a bunch of times it doesn't work and it's really not clear why. A shame because as you say, when it works, it works great.
I used to have this with airdrop all the time, and handoff too. So much potential but never really worked well. When it works it feels magical, but most of the time I just ended up being frustrated and copying things up and down via dropbox.
