RHEL 6.2 Server vs Workstation

I have wondered what the difference, at a cursory level, was between the Workstation and Server version of the Red Hat flagship product.
As you may have guessed, the Server product has a number of additional Server-based packages, and the same goes for the Workstation product.

I did the following
(I inserted the appropriate media in my machine)

# ls /media/RHEL_6.2\ x86_64\ Disc\ 1/Packages/ > /tmp/RHEL_6.2-Workstation

# ls /media/RHEL_6.2\ x86_64\ Disc\ 1/Packages/ > /tmp/RHEL_6.2-Server

# sdiff /tmp/RHEL_6.2-Server /tmp/RHEL_6.2-Workstation | egrep '<|>'

# sdiff /tmp/RHEL_6.2-Server /tmp/RHEL_6.2-Workstation | egrep '<|>' | wc -l

The "big 3" differences appears to be that Workstation includes OpenOffice, hyphen and Evolution.  Server includes cluster, and misc infrastructure type products.
