It's taking a newly released mobile- and mini-PC-focused platform that's usually paired with proprietary technology, and building something that's as close as possible to a standard desktop with it. Seems very much in the Framework spirit once you account for that side of it.
Right, but why go with mobile at all? I get the laptops.
For desktop you already have thousands of choices though and reparability, assuming its not some proprietary Dell/HP desktop, is already as good as it gets without breaking out your soldering iron.
That said, they'll know more about the market demand than I do and another option won't hurt :)
