2024-04: got two backpacks "for free" with the Lenovo reward points from buying the <Lenovo ThinkPad P14s gen4 amd>, not bad, that was already cheap and now I got some extra swag:
* Lenovo Select Targus 16" Sport Backpack: https://www.lenovo.com/gb/en/p/accessories-and-software/cases-and-bags/backpacks/gx41l44751[]
* Lenovo Select Targus 16" Mobile Elite Backpack: https://www.lenovo.com/gb/en/p/accessories-and-software/cases-and-bags/backpacks/gx41l44752[]. Measured weight: 1070 g
The sport backpack has a fatal flaw: no strap to hold laptop in place, wo it just tumbles back and forth as you walk.

Neither of them have very good padding below the laptop, but at least the Elite one has a slightly elevated inner bag which woudl likely help a lot in case of a drop.

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:

Specs:
* Processor: <AMD Ryzen 7 PRO 7840U> Processor (3.30 GHz up to 5.10 GHz)

Upon arrival:
* Weight: 1490 g
* Charger weight: 323 g
* Firmware according to `sudo dmidecode -t bios`:
  ``
  Vendor: LENOVO
  Version: R2FET33W (1.13 )
  Release Date: 09/08/2023
  ``

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...
