I had a T420s I think? It got me well through college and for some years after, although I eventually retired it. It was a workhorse that stood up to a lot of abuse being thrown around in my backpack every day. After I wasn't using it all the time I set it up as a dedicated server to mess with and kept it constantly plugged in and running for a few more years. I remember when the screen broke I got a perfect replacement for less than 40 dollars, and it was trivially easy to take the old one out and install the new one with a regular screwdriver and no other special tools. Similar experience when I broke the keyboard, easy to buy a new one and swap the whole thing out myself. I think I also replaced a battery when one started to drain a bit too quickly and the battery of course was something you just pop out and back in. Now with my new MacBook any of those is easily hundreds of dollars plus either needing a trained repairman or seriously risking I break something using specialized tools to melt the glue or pop out the bezel or something like that.
