My take on having much greater than I 'need' speeds. 1Gbsp Fibre symmetrical. I'm wondering when I'll be able to 'test' 10Gbps...
First is the cost difference. Today, for 1/15th of the speed, a 'normal' customer pays $10 less a month. That is a benefit of being a long-term customer with the same company (over 25 years).
Second is the fact that the additional speeds come with further benefits. Such as unlimited downloads/uploads. That comes in very handy when I'm connected via OpenVPN back to my router whenever I'm outside the house (always). Even if I never come close to 10% of those limits, this is still a bonus for peace of mind and not having to worry about being over/short of MBs of data.
The third is the time savings when downloads are required, now. Having the option to pay for a 1-minute download vs. a 15-minute download is a no-brainer to me. The money isn't coming with me when I'm gone, but the time saved sure gives me something tangible while I'm alive. Even if I wasn't enjoying exceptional price cuts, this would drive me to faster internet. And is what made me stay on the faster plans each time I tried them for 'free' for a 6-month term.
A few years ago I had made a Pro's and Con's comparison of the speeds I was paying for then, and moving up to 3x faster speeds. The conclusion was that at that time, I was capable and willing to pay up to 80% more for those benefits. After reviewing the scenario after a few short months, the conclusion hadn't changed. But I was working 2 to 3 days less each month (same pay) with no change in the amount of work performed.
I don't buy/order services online. Nor do I settle for what is the advertised price. I call and I talk to someone in person. I don't threaten to cancel my service, raise my voice nor am I rude. I simply have a conversation with the person on the other end of the line, and if what they can offer is in my best interest, I do it. This has worked to my advantage for the last decade or more.
