I think he already told us: "If Mosso gave OpenSolaris as an option, I would switch to it."

I'm surprised to see it, since the majority of folks prefer Linux by some margin (certainly the userland is better on Linux). But Solaris has some killer features in the cloud space, and Joyent are doing a great job taking advantage of them. Solaris Zones are quite a bit more efficient than Xen, and quite a bit more stable than OpenVZ/Virtuozzo and vservers (which use roughly the same model as Solaris Zones).
