Another interesting thing is the lack of any kind of clock on the top bar. Instead there is a clock in the dock that can be set to either display the time on the dock or in a floating window, among other preferences. It is a separate application as well!

iTunes was not released yet, so instead the Public Beta includes a simple MP3 player, in addition to the already-included Quicktime.

The UNIX underpinnings have mostly been hidden away, but in certain programs (such as the Disk Utility), it is possible to see some of the old archaisms (the /dev folder for example) that are in fact still present. Most of these were hidden even further away in later versions of Mac OS X.

Speaking of UNIX, Mac OS now includes a command line!

Shutting down the Mac OS X Public Beta.
