It's nice that it'll be standardized to an extent as well making it less likely for people to run into incompatibilities, hopefully. Dropping the entry price is also going to be helpful, but there's still so many questions.
The inside out tracking means room scale interaction is handled easily by the headset. However, there was no indication as to how users were expected to interact with the virtual environment. And the on stage demo during the Windows 10 event didn't really show any interaction.
No specs yet. How fast will the screen refresh? How fast will head position and orientation be updated? What is the resolution of the screens?
I suppose we'll have to wait for OEMs to officially unveil their hardware to find out. If the specs are decent, 300 USD might be a good enough price point for me to get one to play with. At the very least, I'd be able to use an Xbox controller to interact with things similar to the Oculus Rift.
Speaking of the Oculus Rift. I do wonder if there will be a way to use the OEM headsets with either the Oculus controllers or the HTC controllers? And how compatible will they be with the current VR software on PC?
If Microsoft can unify and standardize VR on PC, that would go a long way towards driving adoption similar to how adoption for gaming on PC exploded after DirectX matured.
