I read here a lot about how great it is to keep old hardware running with lightweight distros. I myself have an eight year old t410 as my daily driver and it does what it is asked to do.
But, I decided to give myself a treat and bought a T470 2 weeks ago. It is indeed a completely new experience, particularly when it comes to overall speed, internet speed and screen quality.
I guess what I want to say is: if one runs old hardware just for the sake of it, one misses out on a few things.
My t410 will stay as my backup machine that is for sure. But the new kid on the block gets all the attention.
