OpenIndiana is in their what, first release?  I don't think that
Nexenta 3.x is based on it *yet*.

Both will eventually converge.

In the meantime, yes, for storage needs I'd go with Nexenta for the

For personal use?  Maybe different factors.

Nexenta the company of course will be contributing to OpenIndiana and
Illumos...
