Really simple - Plex. I would be happy simply consuming my media on a big screen. I am very curious to see how the image fidelity is, if there is any chromatic aberration, how clear text is, and how convincing it is. I tried bigscreen on oculus and was not impressed at all. The font scaling combined with the display and lens quality made it unusable.

I do a lot of audio/video installations. I'd love to be able to get real-time measurements of spaces I'm working in, and then use an app to "draw" a plan of what needs to go where, etc, that I could export and share with a customer Throw in a visualizer for spatially testing the audio acoustics of the space and I'd sell my soul.

I’d like to try GarageBand especially for drums.
