I also find it awkward and uncomfortable to use, but that might just be me.
You'll note that Macbooks don't quite look the same after Ive left and his influence went away.
How are they different ?
For a while, you could get the thermals a bit more tolerable by undervolting them, but then the plundervolt mitigations blocked that.
(Typing this comment from a Lenovo X1 Extreme sitting on a cooling pad, sat next to an X1 Carbon that we can't use because it throttles too much. :)
Regarding your X1, tweaking Linux kernel parameters and downvolting a bit can work wonders in terms of reaching an pleasant heat : performance ratio. Obviously, Lenovo should have taken care of this. However, they release so many different machines that it's hard for them to pay attention to details.
I replaced the thermal paste with some of that PTM stuff which helped a bit, but not enough. I also found that for some reason it tends to BDPROCHOT-throttle when powered through the official Thunderbolt 4 Workstation Dock, even though it’s meant to be 230W and provides power separately to the USB port - but using the standalone AC adapter when docked fixes that.
Ultimately, until there are some decent X86-64 laptops released, the choice is between slow, thin and quiet vs less slow, but big, heavy and noisy. AMD is a bit better than Intel but still weak on mobile and nowhere near as good as the current Apple offerings.
On another note, why are PC manufacturers still putting fan intakes on the bottom. Maybe it’s theoretically more efficient, but tell that to my users who always do things like resting their laptop on a book then wondering why their Zoom screen sharing goes jittery.
That's not to say your situation is unique...there are probably many machines out there that have not had problems, including one owned by my wife. But there are also an unusually high number of machines that did.
"Cost"
I'm a native English speaker and nobody told me this (and I didn't manage to pick it up) until I was nearly 40. "Cost"'s past tense is also "cost."
There's another, newer, largely fatuous, verbed "cost" that means "to calculate the cost of something." That's the one that gets used in the past tense ("the projects have all been costed.")
"I've costed a keyboard replacement for my computer, and the total is more than the computer cost in the first place."
