I ran into this article by accident and I thought that this might interest if not some, most of you. Nick dePlume has posted the second part of his article, 'Inside Jaguar: An exclusive sneak-peek at new updates, part two' that discusses changes in the latest pre-release build of the next Mac OS major update. Together with this article, are some sneak peak screenshots that would give you the visual picture of the changes that were made.
"Today, we take a look at new updates and changes seen in the latest pre-release builds of the next major update to Mac OS X, code-named Jaguar. In earlier weeks, we've examined the Finder and System Preferences, iChat, Mail and Address Book, Sherlock 3 and Ink, other applications and utilities, scanner support, system sounds, new updates and miscellaneous items, and have answered reader questions, including a second Q&A."
