I've owned a pretty maxed out T420s. When I bought it back in early 2013, it had the standard HDD drive and 8GB of RAM. I swapped it out with a SSD and bumped it up to 16GB RAM, and I can say it still runs pretty well. Aside from not being able to do 4K or having to live with that ugly 1080p screen, it's been just as solid as my late 2016 15inch MBP.

Oh, no dongle anxiety too.

The ROI on it is pretty amazing. Back when repairability was still a thing.
