The creator of Haiku Podcast has made a very nice video presenting Haiku OS, a BeOS-like Free Operating System which is now mostly in alpha stage and can already be used for simple things. This video shows that it's well on its way and I believe it has great potential as a possible future contender in the realm of Free Operating Systems, as they start developing some more exciting things based on the first release of Haiku.
