While this is true, I feel like this tank misses a few things.

• not everyone replaces on this schedule. I still know people that go 2hrs or less on a phone. At the same point, I bought new, used, then passed down to my daughter,my iPhone 6 and she finally replaced it in 2022. It was still getting security updates. That’s 8 yrs. I’m not in a hurry to replace my iPhone 11, it’s still perfectly fine. My late 2013 MBP, still works well. (I replaced the battery once in 2020) I finally upgraded to an M2, but continue to use the 2013 for things at times.

People replace things too often imho. But to go with this theme, I used to do so as well… swapped my iPhone 3GS for a 4s and then the 6. I’d build a new desktop every 18-24 months near the late 90’s and 2000’s. Things were improving so fast in those times, it was worth it… but then things have stagnated. I don’t see a good reason to get a new iPhone, and while I love the M2, it’ll easily tide me over for 10 yrs. My wife still uses her Lenovo laptop from 2011. Cost is only part of the equation. Sure I don’t want to drop the coin, but also there’s really no big changes worth it to me.

I do miss my Nokia 3110 though. Stability and battery life were awesome. Those were simpler days.

I think you want to use hourly cost, or maybe some other measure of the utility of something. I can own a rock, and it may be a magnificent rock that will last centuries, but it isn't going to give me much benefit.

Same with an old cell phone. I may be able to use it for 8 years, but I'm not going to use it for navigation, taking pictures, video chatting with family/friends, replacing my laptop when I'm out, etc.

Your table is a good start, but it's missing some really important information
