I know of two "best laptops ever made":
Drew DeVault says it's the X200:

« The best laptop ever made is the ThinkPad X200, and I have two of them. »
He has a very strong case. I own one. It is certainly one of the best ever.
On the other hand, Brad Taunt says it is the X220:
« The X220 ThinkPad is the greatest laptop ever made and you’re wrong if you think otherwise. »
Ulaş Türkmen agrees:

I also have two X220 machines, and I use them more than the X200 now. They still work perfectly, while my X200 is getting flakey. (Although with its SSD and 8GB of RAM, it runs Alpine very well indeed and could be a daily driver.)
The X220 has a slightly shallowed screen; that's a weakness. But mine are 100% usable: between them, I run Haiku, FreeBSD, OpenBSD, Ubuntu, and Pop OS, and all of them go like stink and are daily-drivable on this 2011 hardware.
