re: 8 Apple Changes That Matter
The need to "bump" is indeed very limiting. If you want to bump several people you need to go look for them. With Airdrop, you can send to a number of people at once. You can do so as long as they are on the same network. So they could be on the other side of a crowded room, or even in another room on another floor. No need to go looking for them.
As far as Samsung's Ad went, no, you can't bump so done in a car and have them drive away if you're sending them anything other than a very small video. They must stay withing range until the entire thing is moved over.
