Which distribution do you like the most?  I personally have 5 I play with, Xubuntu, Zenwalk, RHEL 5, SLED 10 and Oracle Enterprise Linux.  I personally like Zenwalk and Xubuntu as my favorites of them all but which one in here is the favorite?  for my traditional UNIX boxes I have BSD and Solaris 10.  I also have an older AIX box but I dont use it much.
