How old? IBM Thinkpads were often decent enough that I'd pick one up if I saw a good deal, but Lenovo makes them now and they've got a long history of pre-installing malware and backdoors in their products (often in exchange for money). It's a shame, because I hear they play very well with linux.
I'm not sure a Lenovo device would be any safer than the latest processors
Source for this?
They don't all ship with malware infested UEFI so that even reinstalling your OS won't remove the bloatware they installed. Also Lenovo has, multiple times now, installed adware on systems that seriously compromised the security of the user and/or the device.
Adware is bad, remote code execution is much worse.
Any luck is to uefi based malware?
(Personally I prefer a nice old fashioned bios)
Superfish was bad enough, but once the public became aware that the malware existed and was so insecure that it made their devices vulnerable to be hacked Lenovo provided people with a fix to remove the malware, but it left the security vulnerability that the malware introduced to the system in place leaving everyone to think they solved the problem when they were still vulnerable. People had to track down news articles and social media posts for information on how to correct the problem until Lenovo updated their instructions.

Who said slow? OK, no Google Earth but I can use some TCL/TK based OSM map viewer from the TkIMG demos, and no Wine to play the games for that era. But, meh, I only get GL 1.4, not enough for proper DirectX9 translation (GL 2.1 it's the true basic DX9->GL mapping), so I've got lots of libre alternatives from https://osgameclones.com and a custom ScummVM compiled from ports with --enable-all-engines added to the configure script so I can play games from the Apple II era, passing thru Ultima IV, Maniac Mansion, Broken Sword up to Blade Runner and, soon, Sanitarium.
