The thing is, it’s not easy being Apple. You have to write one operating system that’s supposed to please everyone, from the self-employed first-time newbie to the network administrator for NASA. You have to design a networking system simple enough for the laptop owner who just wants to copy things to a desktop Mac when returning from a trip, yet secure and flexible enough for the network designer at a large corporation.

That’s why OS X offers three ways to share files, striking three different positions along the Simplicity-to-Flexibility Spectrum:
The easiest way: AirDrop. This feature is dreamy—if there are other people in your house or office who have wireless Macs running Lion or later. Imagine this: You open the AirDrop folder, where you see everybody else’s icons. To give someone a file, you drop its icon ...
