I agree that pricing might be their biggest challenge. Matte 4k X1 Carbon ThinkPads in like-new condition go for around $1k on eBay, and they run Linux fine, so long as you're willing to install non-free firmware. I'm not sure what kind of premium I'd be willing to pay to get the faster boot and libre firmware from a company with no track record at all in the marketplace. I've recently upgraded the SSD in my T480s that's running Debian, and I figure I have another 2 or 3 years before I'll feel the need to go shopping for something better. Maybe when the used ThinkPad T14 Gen 3 AMD machines start hitting eBay in force.
I also own a Framework laptop, and the 3:2 aspect ratio is a killer feature for me. It's really hard to go back to 16:10 after using that for a while.
