To further promote the release of Mac OS X 10.5 Leopard, which Apple Incorporated has announced will be available on October 26, the company has posted a guide tour to promote the release of the latest version of its operating system. The video goes through various features, old and new, of the OS available only on the Macintosh. A single-user license costs $129.00 direct from Apple while a five-user license will set you back just $199.00. Customers who pre-order OS X v10.5 from Apple are guaranteed to have their copy on their doorstep on the day of release, which is now just a week away.
