Very true. I pay for 80/20 Fibre unlimited and that currently does me but I keep on finding that things are using more and more. Yesterday, I downloaded a Windows update, 925mb if I remember right. Took about 3 mins or so. On the old ADSL, I'd have been waiting hours. And we have 3 boxes that will have that update.
Once I used to think 10Gb a month was ample. Within the first month of us going over to fibre we were nudging 200Gb. We might go up and down slightly but that has become a norm for us and we haven't even started downloading 4K stuff yet. I don't ever download films, just stream what we want to watch, no buffering etc. We also make loads of free video calls to the other side of the world, brilliant. Makes the landline a bit of a dinosaur. Never use it.
Price wise I'm paying about £10 more than when we were on ADSL (1.2Mb/s). Faster speeds coupled with unlimited is a no brainer, even if it costs just a bit more. I can guarantee you will
use the speeds. But then you look at one ISP ad, faster speeds, queue dad playing game, girl singing to her friends etc and in the small print, 30GB a month cap. Dream on.
So yes, faster fibre, bring it on but don't go too mad with the price or the cap.
