I first mentioned the Zeta OS a few months ago when word of the beta was spreading around. Zeta is the continued effort to revive the cool BeOS which still has a big following even though the operating system disappeared from the scene several years ago. Zeta takes the BeOS to the next level and updates it to take advantage of hardware advancements and it looks pretty nice. Ars Tecnica has a new review of Zeta 1.0 that is very thorough and gives a complete picture of the innovative OS from installation to working with the interface. If you are interested in Zeta or just reminiscent about BeOS give the article a read.
