Even if the internal USB-C ports which the expansion cards plug into fail, which to me also seems like a long time away, the mainboard is designed to be replaceable so I think you'd be in a better position than with another laptop with a failed power plug.

There are also clips that hold the expansion cards in place. My HDMI one started coming out when I unplug the cable even from really early on, even without pressing the button which should be required to remove the card. That is another way they could fail - in getting loose enough that they weren't securely held in place to be useable. The internal USB-C port would still apply some force in holding them in place though. In my case, this is not related to the socket, but to the card. I'll need to open it up and take a closer look, but hopefully they're designed so the cards fail long before whatever is in the chassis which holds them in. Plastic on the cards vs metal on the chassis would seem robust to me. Otherwise, if the mechanism fails on the chassis side, that would be a much bigger replacement.

Disclosure: I was a big supporter of Framework and bought an early 13 inch (11th gen Intel). I would no longer recommend them due to the mounting list of problems I've had, and despite their responses always being friendly and prompt, they are unable to send any replacement parts, because I've moved to a non-supported country and there is no way they can send anything to the maritime capital of the world. I try to be neutral in my comments, but sarcasm creeps into my disclosures.

Your last paragraph is exactly why I'm avoiding the brand.

It's a premium product with subpar service.

You have Framework the ideal. Right to repair , replaceable parts, ownership rights.

Vs

Framework the company, weird QC issues, parts out of stock, iffy supply. Prices so high you might as well just buy a better laptop whenever you'd swap the main board out.

I think I'm just going with a Thinkpad for my next computer. I also prefer the all black look.
