Sounds about right to me. We have had gigabit switches available to consumers for over a decade and everything faster than that is still considered business grade. All the while the price has not dropped in any significant manner on gigabit switches or anything faster than that
That is 100% INCORRECT. Gigabit switches are much cheaper than they were 10 years ago. In 2004, a managed layer 2, 24 port gig switch with no POE was upwards of $1500. Today I can buy a 48 port HP Proliant switch with POE+, expansion slots for 10Gbs and layer 2/3 management for less than $1000. As for faster tech such as 10Gbs, its not that expensive to manufacture but it is difficult to implement on non ventilated systems. The processing units required for 10Gbs requires proper cooling and the link is far more sensitive to EMI and cabling defects (such as a kinks). Want proof? Do this test. Take a 50ft wire, crimp the ends without crossing 4,5 between 3 and 6 as specified in 568B (Basically go 1, 2, 3, 4, 5, 6, 7, 8 on both sides). Then go and connect your computer to a Gig switch. You'll get a link but won't be able to pass data. Now go into your setting and set the speed to 10Mbs Half Duplex. Boom, you're connected. Try 100Mbs. You'll probably get connectivity but it will be slow (20Mbs transfer speed roughly). Now, shrink that cable to 10ft. Try Gig again. It will work but won't give you the full yield. Now you understand why a pair of wires can't get you the speeds you want them to deliver to your house.
But all this is aside the point. There's no need for end users at the moment to have gig connection to WAN. They need gig for LAN and that's about it. Getting 100Mbs to their home requires fiber or multiple pairs to be used. Multiple pairs means you need to upgrade all COs and the end equipment is about $600 per house. That alone makes it impractical an costly for the typical user. Getting fiber from the CO to our business (less than 1000ft away) was going to cost $5000. This is the cost of trenching + installing the wire + bringing it at the demarcation point. Now image how much it would cost for you to get your house wired that way with possibly being 5000 ft away.
All this being said, I know how telcos think and they aren't innocent. This is why I think regulations on internet services and cost are necessary to force them to evolve and innovate. Normally competition would force change but because the infrastructure is owned by said entities it will change slowly.
