The most important new feature added in Leopard is undoubtedly Time Machine, Apple’s attempt to encourage the vast majority of users who never, ever routinely back up their data to change their ways. Time Machine automatically backs up a Mac’s files to a separate hard drive (internal or external, though external is certainly safer and more convenient) or a network volume being shared by another Mac running Leopard. Attaching a drive and assigning it as a Time Machine backup volume is incredibly easy, and once you’ve set it up, you can essentially forget all about it.
It’s been 18 months since Boot Camp, Apple’s method of allowing Intel-based Macs to boot into Windows, was released as a public beta. Boot Camp serves a useful purpose in that it provides basic Windows compatibility and the ability to run Windows programs at native speeds.
Multiple-workspace utilities, which let you switch between various collections of application windows in order to reduce clutter, have been around for years on numerous platforms, including Mac OS X.
Quick Look, which appears throughout Leopard, is a technology that lets users preview the contents of documents without opening the program that was used to create them.
