Bought: November 2023 during Black Friday sale for £1,323.00 to be <Ciro Santilli>'s main personal laptop.

Six years after, and we are 2x on every key spec (except processor Hz ;-) at about 1/2 the price and 1/2 the weight (though smaller 14" screen for greater portability), so not bad! Customized to max out each hardware spec:

Upon arrival:
* Weight: 1490 g
* Charger weight: 323 g
* Firmware according to `sudo dmidecode -t bios`:

  Vendor: LENOVO
  Version: R2FET33W (1.13 )

Buy research:
* https://www.phoronix.com/review/thinkpad-p14s-gen4 says Ubuntu running fine
* Intel vs amd: the Intel ones could come with a discrete rtx A500 GPU. GPU likely makes laptop heavier and less power efficient. And both have basically the same benchmark which is crazy:
  * https://www.videocardbenchmark.net/gpu.php?gpu=RTX+A500+Laptop+GPU&id=4649
  * https://www.videocardbenchmark.net/gpu.php?gpu=Radeon+780M&id=4818
  So the only downside is not being able to run CUDA.
* thought about Yoga or other Ultrabook options, but 2x price at same specs, so nah...
