To date, framework's laptops are the only ones I've ever seen that were designed with replacing the motherboard as a possible upgrade path. There are a few Thinkpad series out there that by happy coincidence, you can swap parts and upgrade screens or maybe change to a newer generation's motherboard.. but generally that's more of a coincidence and not an intent.

I'm glad framework is trying this out. I'm not surprised about the battery life, but pretty much anything not made by Apple will have that issue lol.
