That's a really good price, I have the Gen1 and I'm happy with it, When I went to buy the machine, I got near the top end, i.e., 4k screen 1TB storage 32GB of ram (even though I don't need that much). While I could have configured the ram lower, the shipping was faster with the stock configuration. I wanted the 4k as ell, but now after using it for a year, I find that 4k on a 15" form factor isn't ideal and a FHD screen might be better.
Overall I have no regrets and after seeing some of the complaints with the 16" MBP, I'm content staying away.
I honestly believe that there is a genuine disorder called Apple Derangement Syndrome, and it's out in full force for the 16" Macbook Pro. Please believe me when I say that. I had the most absolutely terrible Apple experience until I got a 16" Macbook Pro, iPhone 11 64 GB, Apple TV 4K 64 GB, Apple Pencil(1st gen), and iPad Mini 2 256 GB. I had to take my first ever Apple computer in for repair nine times, and after that I did not touch Mac hardware until this 16" MBP. That's a decade of rage towards Apple dispelled by the quality of the 16" Macbook Pro. I have gone through two models of the 16" Macbook Pro. The 16" $2399 base config model, and the $2799 base config model. The only possible downside to this laptop is the fact that the half-size keys, like Esc, and the arrow keys need to pressed in the center to register as having been pressed. But that's such a non-issue. I don't hear coil whine, speaker popping, insufficient screen quality(I prefer using the 16" MBP screen to my 27" 1440p 144Hz gaming monitor), and the keyboard backlight is just fine and I see no problem with it.
It stands to reason that one would expect perfection at an experience that starts at $2399 straight from Apple, but none will ever exist. That EVGA Geforce RTX 2080 Black 8 GB dGPU I bought over the summer should not have been dead on arrival with its horrifying amount of problems. I paid $800 for it! For a video card! EVGA is the most highly regarded maker of Nvidia GPUs for Christ's sake. But the fact is, no matter the cost, in order to meet demand, there will be issues that are just downright unavoidable given the demand that these corporations have to meet. Apple is the most successful tech company in the world and they did not get that way by not having enough product to sell. Would I have preferred a BTO option to cut a few buckaroos off by not having a Touch Bar? Yes. Would I have preferred a cut down 5600 or 5700 in this $2799 machine? Yes! And naturally, the debut of iOS 13 and Catalina made it resoundingly clear that Apple had put meeting a deadline before providing a solid experience. But the same can be said of any operating system.
Windows 10 did not meet the expectations of Windows 7 diehards. I find no issue with Windows 10 beyond wanting a baked in option to disable what my system shares with Microsoft instead of using a solution like ShutUp!, but what can I do? I for one had the horror of Windows XP 64-Bit Edition thrust on me as a teenager. It was terrifyingly bad. And before that? While everyone was enjoying Windows 2000? I had to suffer through Windows Millennium Edition. I had a Macbook Pro that I depended on for college between 2007-2009 die nine freaking times on me. They finally relented and gave me their new unibody model that had just come out. It wasn't good enough for me. I sold that unibody Macbook Pro on Craigslist so quickly after I received it. And I gotta say, the issues people have supposedly been having with the 16" are either the ramblings of insane people(and I would know as I am on disability for PTSD/major depressive disorder after one too many guns in my face at work), or they are so minor as to not justify the furor being raised about them. and I say that as a person absolutely not stuck in the reality distortion field that the Apple community is well known for.
You clearly don't need a new laptop if you've got the 15" Thinkpad X1 Extreme(Gen 1). The Nvidia Geforce 1050 4 GB is a very stellar card. And if you use headphones with your Thinkpad? It's terrible bottom firing speaker system will have no bearing on your experience. Although, I do share your frustration about the 4K display being wholly unnecessary in a 15-17" laptop. Not only does that resolution chew up battery like it's bubble gum, but it's 4K on a 16" screen! I mean, what's the point!? It's why I'm so flabbergasted by people lamentng the lack of one on the 16" Macbook Pro. The only thing I would like to see in my 16" MBP is window splitting like is present in Windows 10. I do not want to have to go into full screen mode just to have to windows open side by side across my display, lol.
