I think it looks like a really positive first step. Yeah, the resolution is too low but that's solvable with a better headset. It's a bit laggy, but that's probably due to recording video of VR being hard. The windows are weird sizes, but that might be user choice. Heck, I personally don't want to code things floating in space, but that's just a matter of choosing a different background. All those problems are solvable.
There are loads more problems that are also likely solvable too. And maybe some that aren't. We don't know yet. I'm glad someone is working on the problem to find out. That's far better than not having, maybe, one day in the distant future, a VR option to use for work.
