Opensolaris 2009.06 had been released on June 1, 2009. If you want to take a look at the latest version 2010.03, you can follow this link but it is still under development preview.
Here are some screenshots of Opensolaris 2009.06 with Gnome compiz fusion 3D window appearance make it more like Ubuntu Linux. Some improvements had been done in the system, much more stable in compiz fusion, faster reboot or shutdown (comparing to the previous release 2008.11). There is one new application that really interesting, Elisa Media Center (something like Windows Media Center in Ms Windowz Vista or Win 7) however, if you run this application the system will become damn slow :(
Yah, one thing still there is lack of memory management. To run a few application still need more memory resources comparing with Windows or Linux OS. Often the memory load reachs more that 90%. I think the opensolaris developers need to pay more attention to improve on the memory allocation/management in the next release.

I think you’re not that right about memory management.
I’m have used OpenSolaris Build 134 for some weeks by now, and faced similar situations, but different conclusions.
The OpenSolaris memory consumption is always near 100% because almost every kbyte of unused memory is being used by ZPF to cache disk access. When you start big applications, the system must “clear” the cache memory back to application use, causing some overhead. This is not a problem with 8G RAM systems, but on 4G (or, in my case, a Atom300 with 2G) it is.
Adjust ZFS to be less memory hungry and you’ll face less overhead on application startup – but at cost of more disk access.
Where I wrote “I’m have used”, please read “I have used”.
(Yes, I know – back to that little English grammar I used some years ago)
Excellent feedback, but it stated that limiting the ARC cache will also limit the amount of cached data that can effect the performance.
Yes.
Unfortunately, ZFS is a memory hog. People says the ideal configuration for heavy disk uses is 8G for a really good reason. :-)
Of course the ZFS is marvelous, and all that memory is put for really good uses (definitively, it’s not a “lazy programming” issue) but in my humble opinion we should be able to choose to use the older UFS.
On a 2G system it could be a better choice.
