>It doesn't make upgrading impossible. The compute pack is... replacable
It is only replaceable and upgradable if this company sells these compute modules separately. There is no discussion I saw on that website that they are committing to do this and there is no guarantee they will be around to still sell you one in the future. Even if they do, you are locked into their ecosystem.
>The benefit is pretty crucial: friction. If you have a tethered VR headset, the amount of work you need to do to set it up is insane.
I have never used a VR device on Linux and maybe the work involved there would be truly "insane", but I have used a few on Windows and they are basically completely plug and play after you install the software. Although even with the work involved, this seems to be an enthusiast device aimed at techies. If these customers are looking for a frictionless experience, they probably wouldn't be daily driving a Linux machine in the first place.
