said by KrK:If corporate America has failed to deliver 4/1 speeds in the *16 years* since xDSL first became common then I think plenty of criticism is warranted, especially if it is compared internationally. In fact it deserves far more then just some criticism.
But they didn't so fail. ADSL2+ and VDSL2 have only been deployable for about 8 years, not 16, and with any such capital-intensive, forklift upgrades, there has to be adequate demand - customers willing to pay the market rate for the service.
Further, you can't set an artificial bar where the technology does not apply. 4M/1M on ADSL2+ only works out to about 10K cable-feet, in the real world - so again, you're expecting yet another forklift upgrade, where there is no demand.
