14 years as your main driver ? Because that what we’re talking about.

14 is a indeed very long. Let’s instead assume 12, it’s 2013 and you got a top specced T440 with 4th gen i7. That’s actually not bad and the build quality is like a tank as all Thinkpads. Nothing I would use as daily driver myself but having used many other thinkpads of that generation I can see why others are still getting by with it today.

Since we are talking about OS support. 4th gen Intel isn’t supported by Windows 11, so you’d have to upgrade to Linux.

Out of curiosity, how much of that thinkpad were you able to upgrade? Could that be the difference between 5 and 14 years here?
