Looking for a successor to my X230 for NetBSD

Hello all,

I'm considering buying a "new" used ThinkPad X-series laptop to run 
NetBSD and would appreciate hearing about real-world experiences from 
others.

My current daily driver is a ThinkPad X230, which has served me very 
well for many years. However, it's starting to show its age, and I'd 
like something with better battery life, a higher-quality display, and 
more modern hardware while still keeping the compact form factor that I 
like about the X-series.

At the moment I have a ThinkPad X13 Gen 2 Yoga here that I'm setting up 
for someone else with Ubuntu. Unfortunately, neither the Wi-Fi nor the 
graphics seem to work properly under NetBSD, which makes me a bit 
hesitant about newer models.

I'm therefore looking at some slightly older machines, such as:

ThinkPad X280
ThinkPad X390
ThinkPad X13 Gen 1

Does anyone have experience running NetBSD on any of these models? How 
well do things like graphics, Wi-Fi, suspend/resume, audio, battery 
management, and external displays work?

I'd be grateful for any recommendations, success stories, or warnings 
before I start hunting for a machine.

Thanks in advance.

Best regards,
Matthias
