I'll try to take a stab at it for you.

1) Latency.  Like any packet-switched topology, it sucks.
2) Variable sized packets.  From a hardware standpoint, it's a whole lot 
	better/more efficient to use (reasonably sized) fixed-sized
	packets/cells/etc.  If you've built hardware you'll realize
	that variable sized things Suck Ass.
3) 2.5Mbit...10Mbit...100BaseT4...100BaseTX...1000BaseTX...10GbE PHY...
    .... BLASTOFF!!

   Wow, too many incarnations, reimplementations, small modifications.
