The new features in 
Solaris and its legendary stability have convinced me to give it a try.  
It has quite a few differences from Linux, some of them obviously better and others that are quite obnoxious to a seasoned Linux administrator.  What follows are some notes on a sample configuration setting up RAID and ZFS on a pair of 80GB disks.  I used Solaris 10 06/06, 
this short howto for the RAID information (with quite a few modifications for Solaris 10), and lots of man page reading.
I expect to follow this up with more notes on Solaris in the following weeks.
