Are you sure about those patents? Those would be expiring in a few short years anyway, 10 GbE is more than 20 years old and 10GBASE-T will be soon, too. Though 10GBASE-T just doesn't feel like a super-sensible PHY to me.
what is the primary use you would have for them? do you have a 10GB connection? if so, very lucky
Probably NAS transfers or similar.
I want a network with that much bandwidth but prices are astronomical.
Ethernet != Internet.
I have a few SFP+ 10 GbE connections internally that are useful for large file transfers.
