Mossberg likes Leopard better than Vista Apple has released a new version of its OS X operating system. Called Leopard, it replaces the previous version known as Tiger.

The Wall Street Journal’s tech expert Walter Mossberg says it builds on Apple’s quality advantage over Windows. In his view, Leopard is better and faster than Vista and has new features that make Macs even easier to use.

Among them are Time Machine, which automatically backs up the entire computer in the background. Cover Flow and Quick Look allow rapid viewing of the contents of files without opening any programs, and its Boot Camp program for running Windows on Mac are built into the new OS X system and work very well.

The Leopard upgrade costs $129 and works on Macs up to six years old.
