The rabbit bit
I read those three words and my mind assumed you were a Cockney referring to the end in which you speak 
We don't use ours much and I keep intending to make plans to dump the PSTN (standard talk infrastructure) element of it, but we're definitely keeping it for stable high-speed broadband provision. We're currently with a broadband company that only offer VoIP options and with another company for the calls package, so should be easy to get rid of the latter and save ££s each month.
I do think there's a bit of a problem, though - with this and all other kinds of progressing technology - as there are always assumptions that 'nobody uses that anymore', when in fact, there are plenty of people - overwhelmingly elderly - who DO still rely on the tech that they're comfortable and satisfied with, who often then feel cut adrift when it's just taken away from them by (mainly) younger and more tech-savvy people who assume that nobody wants it anymore.
We've found that recently with SD television. I'm sure most people would consider us dinosaurs, but we've been happy with it for ages. We've considered switching to HD for some time, but it's never been top of our priority list; and most of the additional gimmicks functions that it comes with are of no interest to us, although they do bump the cost up.
Obviously, we'll have to do something - and I am tech-savvy enough to be able to research it and make the change, when I get around to it - but I wonder how many elderly and vulnerable people will have just seen their regional BBC channels disappear without any advance notice at all and might be distressed that 'the telly has stopped working'. Especially as the elderly are proportionately more likely to pay for a licence fee to a corporation that now only seems to care about the young.
The landline thing is all going to come to a head in the next two years anyway, as traditional PSTN/POTS landline services will become a thing of the past by 2025. Everybody will have a broadband line - with voice services through VoIP only. Again, there's been very little publicity about this - but then, again, those most affected will be the elderly; and presumably it's just their own 'fault' for getting old. Something else that worked just fine but will be stopped working because of 'progress'.
It may provide the encouragement to those without the internet to start getting engaged online, but I think many may go the other way and end up feeling alienated and confused by it all. As an equivalent, I think it's a bit like forcing everybody to buy, maintain, keep and run a car in the name of progress - when those who only travel occasional short distances just want to pay their fare/flash their bus pass as they go and not have all the needless tied-in hassle.
