Apple's Mac OS X version 10.5 - known as Leopard - accomplishes the two things one wants when upgrading to a new operating system: it adds a great deal of value and remains familiar.
The sixth main release of Mac OS X is not offered in basic, premium or ultimate editions, in which the cheapest software offering has the least number of features. Everyone gets the more than 300 new features packed in Leopard for just HK$1,000 (single-user licence).
Stacks appeal
Its gorgeous, redesigned desktop interface, called Stacks, brings a clean, snappy way to organise files for easy access.
Web, e-mail and other downloaded files are automatically placed in a Downloads stack for a clutter-free desktop.
The improved Mac Finder includes the new Cover Flow, a 3D graphical user interface for visually rummaging through files and digital libraries. Quick Look lets you view documents, photos, videos and other files on the desktop without having to open the application that created them.
