I would guess that a full 80% of 2014 5k iMacs have been retired, of that number I would also venture to say that at least 75% of those have or had perfectly functioning screens at the time they were retired.
I didn't say Intel iMacs will last a lifetime, I said Apple Silicon iMacs are going to last a lifetime. Just as Moore's Law indicates exponential growth in transistor count, the useable lifetime of those computers grows too.
There is absolutely no reason not to extend the life of these devices by another 5 or 10 years as a monitor.
The lifetime was already 10+ years for Macs built in 2009. A 2021 iMac will easily last two decades and more.
M1 iMacs, like most consumer computers, will be nearly useless as a daily driver at 10 years, if one is lucky. Think you are going to get away with 8gb RAM or 256 gb SSDs in 10 years? That is laughable!
8 GB RAM was enough in 2009 and is still enough. The only reason to retire old iMacs is heat, energy consumption and fan noise.
Why aren't you using a Gen1 iPhone? If you are into generational hand me downs, perhaps you could make use of an Apple //c as your daily driver?
You really don't understand the concept of technological progress, do you? I don't use a 2007 iPhone, because they didn't even sell those in most countries at that time. And I didn't want to waste my money on a 1st generation device. So instead of an iPhone I bought my first iMac in 2009 and that one is still in use as my mom's streaming TV. Yes, those monitors last a long time, but so does the computer inside.
LOL, another silly statement. I spent 20+ years in IT so I am more than computer literate. Smart monitors, as an example the new ones form Samsung, are not only spying devices that report usage back to the mothership but planned obsolescence in that the screen will outlive the "smarts".
The iMac is a smartmonitor, because there's a computer inside. Just like the iPhone is a smartphone, because there is a computer inside. Samsung's so-called "smartmonitors" are like Nokia's so-called "smartphones". Smart in name only, but actually dumb feature phones. A real IT nerd wants a programmable computer in everything, every light bulb, every power socket, every thermostat, door bell, window blinds and of course every monitor. Why would I want a monitor in my house, which I can't program to do what I want?
How many smart TVs no longer receive app updates after only a couple of years because the TV manufacturers used the least common denominator parts for the smarts?
All TVs are dumb. That's why I don't have a TV, I have an iMac.
I highly doubt many 8-10 year old TVs are receiving app updates.
And no computer-literate person cares. Those are not computers. Not smart, not a good purchase.
The list goes on, how many G1 Apple watches are still in use?
Still this silly idea of buying a 1st gen. product. My current iPhone is five years old and does 98% of what an Apple Watch can do. Why the hell would I buy one of those?
My daily driver is a 2016 Samsung Plasma with an AppleTV, don't want or need anything more. In my office I have a Samsung 4k "smart" TV that is not allowed to talk to the intarwebz and also has an AppleTV.
That's four dumb devices. You yourself put the "smart" in quotes. Buy a real iMac!
