"  Anyone who wasn&amp;#039;t trapped under something large and opaque for the past few months knows that Microsoft recently launched its Vista operating system (OS), which has many similarities to Apple&amp;#039;s groundbreaking OS X. Interestingly, Vista will not be the only big OS launch this year. Apple is bringing out a major upgrade of its own. Code-named &amp;quot;Leopard,&amp;quot; OS X 10.5 is due out this spring, bringing with it new features such as Time Machine, which backs up files as you save them so that you can restore deleted data; a new organizational system called Spaces that groups open applications to avoid clutter; and a layer-based Core Animation engine. Leopard will be included on new Macs, but older OS X&amp;#039;ers will have to pay for the upgrade -- no price has been announced, but all past OS X&amp;#039;s have cost $129.
