> When we first started Mighty, our plan was to stream Microsoft Windows. But after talking to users we learned that they were using their browser most of the time and what they really needed was a faster browser

I'm at the opposite side of this, wish they streamed Windows or macOS. Nothing that I personally run in the browser is ever slow (at least not because of local hardware resources), but desktop apps like Photoshop, After Effects, Premiere, Houdini, Cinema 4D, Blender are slow all the time (on my MacBook Pro). I guess I'm in the minority, but I'd love pay to make those apps faster instead.
