I work with thousands of their business class Thinkpads and they are also junk. They seem made for corporations to just churn through. I see harware/bios bugs that carry through generations.
Could be. I stopped at the 2011 and 2013 variants. Still powerful enough for me, cheap to repair, and the intel me can be entirely erased/corebooted. I don’t know about the more recent business class TP.
