I have no idea how solaris works since i've never interacted with it, but its a great OS to be sure......... either way maybe in a year or less we'll all see what its worth:
Open Solaris is a Linux killer
Sun says OS will be as common as muck

SUN CLAIMS that Open Solaris will give Linux a good kicking and will soon be as common as Java.
Marc Hamilton, vice president of Solaris marketing, is positioning the operating system as a rival to the Open Sauce Linux. He claims that the operating system will boldly go where no Solaris has gone before and would be even coming to a desktop near you.
Hamilton admits that before that happens, Sun has to convince developers that the operating system is a cuddly bundle of fun and not something they would hate to get as much as Bird Flu.
According to ComputerWorld, Hamilton thinks there is an "enormous momentum" building behind Solaris. When momentum build behind you it usually means that you are about to be stabbed: ask Julius Caesar.
Another Sun bloke behind Open Solaris is Ian Murdock, who is chief operating platforms officer at Sun. However he was behind an "enormous momentum" at the Linux Foundation and was headhunted to take the lessons he's learned in the Linux community and apply them to Solaris.
Sun will release the Open Solaris binaries early next year in a distribution code-named "Project Indiana" that will be similar to Linux distributions. µ
