Apples and oranges
As many others have stated, gigabit and even high-hundred-bit downstream speeds are excessive for most users currently but the infrastructure still needs to be in place for those who may require it now and for the requirements of the future as technology, such as Ultra High Definition TV, evolves.
I had a 150Mb/s downstream fibre-to-the-cabinet, coax-to-the-home connection with VM which I attained through a series of free upgrades from, IIRC, 10Mb/s to 20Mb/s then 100Mb/s and ultimately 150Mb/s over about twenty five years. However, the upstream speed has remained at a nominal 6Mb/s due to the historical limitations of DOCSIS networks. There are higher downstream speed packages available which include a moderate upgrade to the upstream speed but hopefully, when VM rolls out DOCSIS 3.1, there will be a better ratio of upstream to downstream or even synchronous data rates.
I downgraded my connection to 100Mb/s last year to save money and even that is still superfluous to my needs although I would like to have a higher upstream speed. I run multiple computers with a variety of operating systems, numerous handheld devices and other internet connected equipment and I'm just beginning to experiment with VoIP. I can still survive quite happily with my 100Mb/s connection though.
The immediate aim should be to provide a minimum offering of 25Mb/s downstream and 5Mb/s or, better still, 10Mb/s upstream nationally. Then, where feasible, packages of 50Mb/s, 100Mb/s, 250Mb/s and upwards should be offered with a minimum downstream to upstream ratio of 5:1 available in those packages with 1:1 options being the ideal goal. Like the energy companies that had hundreds of gas and electricity tariffs, the telecommunications companies need to be told to have simplified, comparable plans and easy switching between alternative providers.
Although cable companies, such as VM, don't offer service everywhere yet, the OpenReach network combined with satellite and microwave providers should offer sufficient choice for everyone by 2025. However, ridiculous races to provide unnecessarily high, commercial rate speeds at the expense of offering reasonable speeds to a wider area of the country should be discouraged.
