Today I installed Solaris 10 on my Sony Vaio Laptop. It reminded me of having a blood test. Not particularly painful, but unpleasant. I felt relief when it was over.
Why did I do this? Well, many sources tell me there are millions of downloaded copies of Solaris, but are they getting used? Did they morph from download to install, with a potential to become a support subscription? From my experience this "path to profit" could be easier. For example, I would have liked more options to change my installation choices, and a clearer explanation of what the installer was waiting for when things appeared to stall. To summarize: "good work but could do better".
On the upside, OpenSolaris is looking very tasty indeed, with its hugely important ZFS filesystem and BrandZ containers for RedHat Linux. The sooner this becomes production-ready, the sooner the Linux wave moves over to Solaris.
