Wow.

I've been using Apple's new Leopard operating system for a couple days now and all I can say is that Time Machine alone made it worth the purchase price.

Time Machine is the backup software built into OS X 10.5 that everybody is raving about. Count me in too. Time Machine runs in the background, doing hourly incremental backups of your data to an external hard drive. What makes it so great is that it is painless to setup - just plug in an external drive, and OS X asks you if you want to use it for Time Machine. Click yes and you're done.

I've already used Time Machine twice to rescue files I ended up needing after I deleted them. Apple has made restoring stuff easy too. Even more, the animated Time Machine screen is so compelling that it makes me want to use it. I find myself clicking on the Time Machine icon occasionally just to watch the stars float by.
