I wish Oculinm wasn't quite so boutique. GPD Win 4 handheld and Minisforum UM780 have a port but generally consumer gear lacks it.
TB is reasonably close enough, but Oculink I think should hypothetically be cheaper, since can be a physical link rather than needing fancy USB4 transceivers.
I wonder how radical a departure CopprLink is going to be from Oculink, in terms of form factor. Supporting PCIe 6.0 seems like a mighty task!
