Leopard, the newest Mac OS and the best operating system so far is out for release this coming October. It has 300+ innovations according to Apple, but I will touch on the 4 main innovations which cannot be found in the current Mac OS Tiger.

Desktop. Enjoy your time on your Computer.

From the stunning new Dock to the menu bar, the Leopard desktop overhauls its Tiger look. The menu bar now sports a transparent appearance letting the desktop image take center stage. Dock icons rest on a reflective floor with a bright active application signal. And the look of Leopard extends to all applications: Every window has a consistent design theme, and active applications are even more distinct, casting deeper shadows. Next is Stacks, a brand-new feature in Leopard. Create Stacks from anything you want to access quickly from one place. When you want to see the files in a Stack, all you have to do is click, Stacks spring open from the Dock in an elegant arc for a few items, or in an at-a-glance grid for more. You get to enjoy the time you spend on your computer; uncluttered, neat and organized.

Quick Look. See Everything.

You're in a hurry for a boardroom presentation and you cannot seem to find the files you need. There's not much time left. Enter Quick Look. It gives you the opportunity to take a glimpse of your entire files without opening them. You can see everything, you can even zoom them. Quick Look works with nearly every file on your system, including images, text files, PDFs, movies, Keynote presentations, and Microsoft Word and Excel files. A real time saver for extremely busy professionals.

Time Machine. Go back in Time.

Have you tried using back-up software? At times it can be confusing and needs manual manipulations to be effective. More than a mere backup, Time Machine makes an up-to-date copy of everything on your Mac, digital photos, music, movies, TV shows, and documents. Set it, then forget it. But what makes Time Machine different from other backup applications is that it not only keeps a spare copy of every file, it remembers how your system looked on any given day so you can revisit your Mac as it appeared in the past. Time machine provides peace of mind and security to users in case of computer crashes.

Spaces. Room for everything.

You and I do a lot on our Mac. So when tasks and projects pile up, simply use Spaces to group your windows and remain organized completely. Create a Space for work. Create a Space for fun and play. Create a communication Space for iChat and Mail and a whole lot more. Feel at home. Navigation from Space to Space is easy. Get a bird's-eye view and select the Space you want or toggle between Spaces using the arrow keys. Moving around the house is fun with lots of spaces, so with the computer.

Mac OS has come a long way since its humble beginnings. I just wonder if Apple still has aces up its sleeves the next time around.
