It certainly does, because it gives you a method of running Snow Leopard
inside a virtual machine on a later OS version, without possibly being
in violation of the licence agreement, and without having to use complex
workarounds.
The virtual machine vendors all say that non-server versions of Snow
Leopard and earlier are not allowed to be used in a VM. (VMware Fusion
and Parallels Desktop enforce this, VirtualBox apparently doesn't.)
It is possible to hack around the server-only restriction, but a
reasonably priced copy of Snow Leopard Server means this is no longer an
issue.
Even with Snow Leopard Server there is the significant memory overhead
of running another copy of OS X, as well as the disk overhead of a
second OS X installation. I've tried this with VMware Fusion and it is
somewhat cumbersome getting files back and forth between the VM and
host, since the shared folder and drag-and-drop mechanisms (available in
Windows in the VM) don't work for Mac OS X in the VM. That leaves file
sharing as your easiest way to transfer files back and forth.
Ironically, I found out about this US$20 Snow Leopard Server offer a few
days after having discovered a copy of Snow Leopard Server on sale via
Amazon for about US$90, and I jumped on that as it was too good a deal
to pass up. Not so good a deal now. Of course, if Apple really is only
doing the SL Server sales in the US (or in some markets), I might not
have been able to order it in New Zealand anyway.
