Old IBM ThinkPads were actually nice laptops that held up to a lot of abuse. I can't touch anything made by Lenovo though. They've been caught more than once installing backdoors and malware (sometimes because they were paid to do it).

They've had many security issues since then, including another backdoor in 2025, but Superfish was probably their worst disaster because after it became public that every machine they sold with it was vulnerable Lenovo continued to deny it until they were finally forced to admit it and release a removal tool. That should have been the end of it, but the removal tool just uninstalled the bloatware itself while leaving the system changes it had made which introduced the vulnerability. That just gave the customers who were even aware of what was going on and downloaded the removal tool a false sense of security. Only after the media started reporting that failure did they eventually release a second removal tool that actually corrected the problem Superfish introduced. No way would I ever trust that company
