"When looking for an alternative to Windows most people think of either Apple's OS X or Linux. Of course, these are both viable alternatives but they are not the only options. One way to go is with yellowTAB's ZETA operating system. Though it is not yet very popular, ZETA is the successor to BeOS, the highly regarded OS from Be, Inc. This is a very interesting and beautiful operating system which may not presently be a threat to Linux but it does have more than a few things going for it."
