You must use a different Wayland than I do.
I play competitive multiplayer games with VRR on a 4k240 monitor in a tiling wm with direct scanout. Color management support (HDR, 10bit, anything beyond 8bit sRGB) is also coming along.
I’ve never had a better working setup than this. Everything on X was painful. Even just getting vsync to work properly used to be tricky in some cases.
I agree that wayland does miss features compared to X but a lot of them are conscious design decisions and don’t affect me personally. For example running graphical applications remotely through e.g. SSH or the complete lack of security allowing any application to easily read my keyboard input.
The mainboards work stand-alone. There are free STLs to print a case for it or you can buy a case from them.
Basically replacing the mainboard gives you another small PC to use as a desktop/living room/server device. You obviously still need RAM and storage though.
I own a framework 13 and I replaced the mainboard once (due to an issue, they replaced it) and it took less than 10 minutes to swap. It’s expensive for what it is, but in support of their vision I was willing to pay premium for it.
They also argue that they need these high prices due to low volumes with the goal of bringing prices down to be more competitive eventually.
