No benefit?  I get much better transfer rates through regular FDDI than 
I do through *switched* 100Mbps ethernet.  I have a DEC GIGAswitch, and 
let me tell you that switched FDDI is *extremely* fast.

That's not even talking about fault-tolerance.

Obselete?  It's still very much used in places where fault tolerance is 
important.
