That said, I am upgrading laptops that sold with 2 - 4 GB of RAM to 16 GB, or at least 8 GB. Often I am replacing on old HDD ( maybe as slow as 5400 RPM ) with a faster SSD. That SSD also juices the battery life. So, what I am using is a lot nicer than what the original owner had to deal with.
Many laptops today will not age as well as, in ten years, that soldered on 8 GB is really going to be a bummer.
I use Linux a fair bit which makes a difference. Linux is fantastic on older hardware and the software itself is totally up to date. I use old Mac laptops a fair bit. The version of MacOS they support would be unusable as would the applications that would still run on it. The same is becoming true of Windows.
