Tonite, I watched the live transcript of the WWDC on MacRumors Live and later on I managed to watch the entire Steve Jobs keynote video despite tons of people watching it around worldwide… It’s like I was sitting right there in the middle of the crowd.

As I though earlier, great features were announced about Mac OS X Leopard — the next version of Mac OS — and some of them were absolutely not expected and were a total surprise. One of them is simply breathtaking and is called: Time Machine…

Think Time Machine as version control built into the core of the system. Version control like Subversion but with a revolutionary user interface… nothing geeky — just version control for the rest of us.

With Time Machine, time is really the 3rd dimension of your desktop. You can recover anything as it were anytime in the past. The amazing thing is that you can browse and search in the “past” using a 3D interface to find the right file you’re missing and bring it back to the future.

Just look at an open window and ask Time Machine to show it to you but in different periods in the past. The system work with anything, the Finder, Address book or iPhoto. You can restore the missing piece with a single click on button.

Time Machine is one of the biggest revolution in backup systems. From what I understood it can work on your locacal hard drive as well as on an external or networked drive.

Since pictures show more than words, Apple put a sneak peak of Mac OS X Leopard on their website. See how Time Machine work.

Enjoy it!
