I think 2.5/5G makes more sense in the home setting. No fancy cabling requirements, cheaper PHYs, lower power, and still multiples faster. 2.5G is starting to be widespread in home networking equipment. If you're going to buy 10G ports in your home gear, I'd make sure they also support mGig (it is a much newer standard, despite being slower, so 10G doesn't imply 2.5G or 5G). 10GBASE-T kind of sucks as a standard.
Either way, storage is really the only typical use case, and even there, most home users aren't moving large files around on the regular.
