In their three-year existence (during COVID, no less), they've shipped five different 13 inch laptop models: three Intel generations, a Chromebook edition of their latest Intel generation, and (most recently) an AMD variant. That's incredibly impressive by itself for such a new company, but on top of all that the parts from these systems are interchangeable and readily available at reasonable prices.

Someone with a first-gen Intel Framework can upgrade to the latest AMD model for as little as $449.00, or around $500 for a bundle with RAM and the wifi module that you'll likely also need. If you're willing to stay a release behind (not possible with their AMD variant yet), you can remain almost current for much less money, at least judging by their pricing on their previous-gen Intel motherboards.

I just ordered an AMD Framework 13 to replace my Thinkpad T480. My previous personal laptop was a Thinkpad T410, which lasted me for seven years. My T480 Thunderbolt controller died due to a firmware bug that I didn't update to fix in time. In addition to the loss of Thunderbolt, it's lead to some other issues (such as a ~30-second pause resuming from sleep) that make it annoying to use. Fixing it would require a motherboard replacement, which iFixit rates as "difficult".
