True, but this is OS X.  The dominating use case is solo workstations.  Who uses OS X Server?<p>I'm actually pretty excited to try out homebrew and install everything in ~/ with my new MBP which I'll purchase as soon as the next refresh comes.  Currently I'm still on 10.5 with a system that has been forward ported via Time Machine backups and account copy-on-install going back to a 2004 PowerBook.  The prospect of having a completely vanilla system with all customizations isolated to my home directory is pretty exciting.
