You do really feel this when you're using old hardware.
I have an iPad that's maybe a decade old at this point. I'm using it for the exact same things I was a decade ago, except that I can barely use the web browser. I don't know if it's the browser or the pages or both, but most web sites are unbearably slow, and some simply don't work, javascript hangs and some elements simply never load. The device is too old to get OS updates, which means I can't update some of the apps. But, that's a good thing because those old apps are still very responsive. The apps I can update are getting slower and slower all the time.
