AFAIK they rolled out some laptops and keyboards with it, but everybody I know that tried them gave up for various reasons.

It's hard enough to come up with compelling interactions using it already, adding technical issues and limitations meant enthusiasm died down. Now it's filed as "these fancy things that never really worked right" and attention has shifted to newer gadgets. I think it would be quite hard after that to convince manufacturers to integrate it again, since the first attempt didn't result in much outside the VR use case.

I've been meaning to come back to it and check out what's changed, but there is a long list of things I've been meaning to check out ;)
