I've taken to buying Lenovos. Laptop P53, replacing the previous 10-year-old T410, Desktop M93P.
I usually specify Intel peripheral chips as these seem to have the best compatibility with Linux.
They work well and work consistently longer.
I suppose you could say my motto with my computers as well as with my cars is "Buy twice as good and buy half as often" or looked at in another way "If it works, don't fix it."
