Hey, I have two thinkpads from Lenovo, T510 and W530. Been using T510 from 2014 till now, actually I was having some kernel level issues in Ubuntu on T510, probably it will be fixed, but I just love it, build quality is like tank. I have dropped it sometimes, even the lcd is blacked out from one side but it is still working as good as it was on day one. I have played Assassins creed 3(whole game) with the 'little eraserhead pointer' and many other games, did my machine learning project using opencv and tensorflow on it. The machine was running for weeks training the model at temps above 85C, and I bought second hand, well I can go on for hours, plus W530 is also like a tank, been mining on it, played games on it. All in all, lenovo thinkpads are still a good choice to go.
