I've always said Solaris was a solid operating system, just a sucky distro. Well, since Sun opened up things, OpenSolaris is making new distributions possible.
There are already 4 listed distros:
Of the 4, I've looked at Nexenta, and it looks like the more serious one. It's Debian/Ubuntu based and it's pretty much in a usable state as it is. It comes with a LiveCD, a VMWare image (cool), and the ordinary install CD. And as they proclaim on their homepage, They have 12029 packages available in their APT repository.
Nothing like being able to :
$> apt-get dist-upgrade
On a solaris box ;-)
Oh, and it comes with ZFS ;-)
No zones yet...
