For desktops, I agree completely that fast ethernet is the way to go. Fast
ether hubs are cheaper and easier to wire than cddi hubs (no cross over
cables required).
For a backbone, though, I would point out that FDDI is a token ring
protocol, so performance is always predictable. Ethernet, and fast ethernet
have performance knees. (Actually, I'm assuming Fast Ethernet will have a
knee at around 70% utilization. I haven't tested that it really does).
Also, both Fiber and Copper can be implemented with dual attached rings
which might be an advantage for a backbone link.
