One thing that's fun about this is that BeOS isn't going anywhere.

If you decided to do this for, say, Windows, Microsoft is going to release a new Windows version with new stuff you can't do and too bad.

But BeOS itself is dead, and the Haiku project (to basically make BeOS again, once named "OpenBeOS") is about a quarter of a century old yet seems barely closer to releasing anything. A lethargic snail could sleep walk to the finish before Haiku ships version 2.
