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...
Wow, too many incarnations, reimplementations, small modifications.
It's been reinvented multiple times with each increase in "speed".
