I purchased in December 2022. I have not needed to buy any replacement parts but availability appears good.
At the same time I bought one of my kids the cheapest MSI laptop I could find for school. I just learned some of the keys on the MSI have been working intermittently. I have no idea what to do with it. We didn’t value a laptop for running Microsoft Word very highly and spent the savings on linux desktop upgrades. I can’t say it was the wrong choice. With the Framework it is trivial to check the connector or order a replacement but there was a substantial price difference.
Out of selfishness I would like people to keep buying Framework so they keep their replacement parts stocked but blind brand loyalty is stupid. People don’t need remuneration to engage in a hobby but if they are working for a company then unpaid labour is generally an abuse.
