I've owned an upgraded T480 since they were released, run archlinux on it. It was a decent computer, but despite having upgraded the battery to the largest possible configuration and using all the tricks in the book to maximize battery life in linux - it sucked. The reality is these Intel processors are just a big inefficient hot mess.
I ended up upgrading to the 14" M1 Max, and there is literally no way you can make a comparison of these two machines, they are worlds apart, build quality, screen quality, weight, battery life, single core & parallel processing, speakers, trackpad - everything.
The only thing the TP wins is bang-for-buck on the second hand market, and getting head turns from neckbeards, thats about it.
