I've as well always been happy with Lenovos. I'm currently using an X1 Carbon (4th gen, FHD screen, ~6-7hrs battery) and a P71 (4k screen, in-built nVidia disabled, ~4-6hrs battery) and their fans run only when I'm stressing the CPU (e.g. compiling) and even then I only hear the flow of the air.
I would like to try an X1, but I think the P71 is more my speed. I wish they offered an X1 with the same rubbery feel as the T430u I am using now. I am not a fan of low-frictive surfaces, since my nerves are shot in my left hand, and my right is very insenstive, which has lead to me dropping things lately.
the P71 is very bulky (somehow more than how it looks in the pictures) and its case feels a bit cheap (the case is "real" plastic and if you tap on it below the keyboard it really makes the sound of an empty plastic case) => personally I expected a bit more as it's not cheap (the components I chose are basically the cheapest ones with the exception of the 4k panel and the backlit keyboard).
Additionally some weeks ago, while I was typing, the backspace and "t" keys stopped working out of the blue => I switched the laptop off but 1 day later the keys were still not working => I then opened the laptop and extracted the keyboard (veeery easy - compliments Lenovo) to read the model number to order later a spare part, touched a bit the connector cable of the keyboard and after putting all back together they keys magically started working again.
Saying all this just because I have the feeling that overall it could be that in the case of the P71 the quality might be a bit lower than what's otherwise the case for other models. Cheers.
