Since me and lots of other people here in Latvia have fibre channel (100+Mbps, no cap, no bw limits, ~30USD with TV and phone package) at home, I'm more than certain, that there is no need to go over 100Mbps for a household (i'm not speaking of commercial or startup-ish consumers). If you are used to downloading large files (read: torrents), they arrive blazingly fast. If you are willing to utilize all 100Mbps at all times, you need capable router to handle not only all of bandwidth, but to be able not to choke on hundreds of high speed connections, when using P2P (that is CPU intensive). Also, you can imagine, that i/o speed at 500Mbps (62 megaBYTEs per second) is close to the limit for common SATA drives. And to finish - when you have network this fast, you'll soon find out, that you need some kind of NAS device, since you download stuff all the time.
