I still have my x61s, T460p, and currently running a T14 Gen 3. The x61s is just sitting there awaiting some future project. Hopefully it happens someday. The T460p has become a homelab server. I never should have sold my W500, that thing was awesome. I also have an 11e which is my burner Windows machine for doing sketchy stuff with cars.
you will NEVER understand it fully....
for you t460 is just a webserver, while for me t470s is my state of the art sole machine...
IMO youu undervalue the magic and robustness of those laptops.
