The BeOS is based on the ideas that "One processor per person is not enough," (Jean-Louis Gassee) and that it is foolish for a modern operating system to incorperate a lot of legacy code. The BeOS was written from the ground up by Be, Inc. It is much more efficient than most current OS's because it does not make any sacrifices to backwards compatibility. It also supports most major modern operating system concepts. There are currently releases available for PowerPC and Intel platforms.
