Not old. Perhaps forever young. My T420 is 9 years old, both batteries are shot but that's my 'desktop', also have an X220, identical last-of-a-generation keyboards, with a fresh 9 cell battery for when on the move. Upgraded with SSDs and RAM; probably not great for gaming or video editing, but no interest in that and there's a PCMCIA bay sitting there just for such applications. I can't see myself changing for at least 5 years, and wouldn't change to something that doesn't have an excellent keyboard, which rules out most laptops including and especially Mac, nor something which can is hardened enough to survive being a little bashed on the floor, in backpack, left outside in sun or snow.

Probably not very relevant to you, since Macs don't like being bashed into the floor too much, but the new post-butterfly keyboards are really nice IMO. Way nicer than that of my late 2013 MBP that got a new keyboard last year. They've really fixed that issue for me, and you still get the Touchbar with a physical ESC key, which IMO is a lot more useful than F-keys ever were.
