Shady Amazon reseller seems to have done me right. The warranty from Lenovo started July 29th 2022. This system wasn't sitting around in a warehouse anywhere, apparently. I wish I'd done this instead of waiting six entire months for Lenovo to not ship me one.
Six screws get the bottom off an X1 Extreme, and it was dead simple to add a 32GB DIMM and to slot in a pair of 2TB drives. This laptop is a little bigger than I'd like, but unlike most other laptops with huge (16" in this case) displays, this guy does not flex anywhere. Even the display by itself is rigid. It's not a featherweight (it's 4lbs; lighter than my T470p by just a bit), but rather than feeling heavy, I'd say that it feels solid.
11th generation Intel Cores, even mobile ones, are a bit zippier than the ones in my big desktop, but here I can actually see an objective change; letting Topaz Denoise AI loose in CPU mode, it needs 2 - 3 seconds less per image than if I have my Threadripper do the same work. This machine also has a 3050Ti mobile, but I haven't gotten around to testing that, since I'm still in the process of downloading all the updates and drivers for every other thing I need. I'm downright excited to see the two Thunderbolt ports on this guy as well. I have Thunderbolt drive enclosures and a dock that adds another three displays if I want to set this up as a desktop.
This is the nicest screen I've seen on a Thinkpad. It's 100 nits brighter than the one I'm used to, and I feel like 2560x1600 is a sweet spot for a laptop screen. No notes at all on that front.
The fingerprint reader in the power button is, near as I can tell, instant. That's so, so good. I'm used to the older versions that require a finger to be placed just so in order to work right.
The webcam isn't bad for a builtin. The mic kind of sucks. I don't know what I was expecting. It's tinny and faintly noisy.
I'm expecting to see 4 - 5 hours of battery life, new, out of this guy. The 170W AC brick is large enough that I didn't just have a second one on hand; that's never happened to me before.
And the price was right. $1750, delivered with 16GB RAM and a 500GB SSD (plus the money in the drives and DIMM I swapped in, I guess)..
