My beef with the Framework laptops is that their memory bandwidth is 5 to 8 times slower (depending on the generation, CPU, and RAM) than that of a $1,500 refurbished MacBook Pro M1 Max 64GB.
If we compare like-to-like the rtx 5070 in a framework 16 has 384GB/s on its own, add the 86 and the combined memory bandwidth is higher than a M1 Max.
If you don’t specifically have a memory bandwidth-constrained workflow this doesn’t matter at all and having upgradable memory is still better for most people.
If Framework starts using CAMM modules or releases a Ryzen AI board with soldered RAM this difference is lessened/disappears.
fwiw the asahi kernel and patches are usable from other distros just fine; i've done it on nixos in the past and the linked blog post shows some stuff running on gentoo
