I've had my current laptop for "everyday" use (a Thinkpad, naturally) for well over a decade. It's very much a "laptop of Thesus" with the only original components being the top and bottom covers. (Bottom modded for extra airflow, top optimally stickerbombed.) I can't really imagine writing or web browsing on a different device. (Portable computer, that is. Work is done with one one of my mechanical keyboards.)
