From BeOS package:
BeOS is stable
Former CEO of Apple Europe, Jean-Louis Gasseé came up with the BeOS project. The central idea was simple and powerful: restarting from scratch and develop the most reliable system. Written in C++, BeOS is object oriented. It is a dynamic, responsive and well thought operating system, which takes into account all your needs and torments.
BeOS is easy to use
BeOS is very easy to use. You will make friends with your PC again! Moving around applications, folders and files is a piece of cake. BeOS is convenient, intuitive and well designed. Create multiple virtual desktops. You can have up to 32 workspaces active at a time, and switch between one another. This will change the way you look at ergonomy!
BeOS is easy to install
Install BeOS right alongside Windows, Linux or Mac OS. At startup, just choose which system to load. It is that simple! You can even read and copy data from files created in other operating systems to BeOS.
BeOS is a multitask system
Launch applications, run multiple audio and video streams, burn audio CDs, print, access menus, switch between windows, go on line... With BeOS you can do many actions at a time. There is no waiting for commands to finish executing. BeOS boots in less than 20 seconds and applications load faster than ever.
BeOS is a multiprocessing system
Designed from the ground up to handle high-bandwidth digital media, BeOS delivers unprecedented speed and power on Intel-based computers. BeOS is the only operating system that lets you take full advantage of 1 to 8 processors. You can boost performances by nearly 100% by adding a second processor.
BeOS support protected memory
With BeOS, each application runs in its own protected memory space. If one application crashes, the system and other applications don't even flinch. Just reload the application that crashed. Need to install a new application or tool? Do it without rebooting. You can even add hardware on the fly.
BeOS is Internet oriented
Thanks to its fully integrated TCP/IP protocol, BeOS offers immediate access to the Internet. Messaging and Internet browsing tools are built-in (not locked in). Any BeOS system is able to serve up web pages right from the start.
BeOS and Open source
You are a developer? Be Happy! BeOS includes all the tools you need to develop applications. You, lucky! Be Inc. decided to give open source of the Tracker and Deskbar.
