Ask HN: Vision Pro Desktop Experience vs. Sidecar

Can anyone comment on how good of an experience it is to use your Macbook Pro desktop on the Vision Pro?

I've tried using Sidecar in the past to get my desktop on my iPad and results were:

- It changes the resolution on my Mac to something much less pleasant in order to work

- Slows my Mac down incredibly while it's sharing the display

- In general just made the whole system a lot slower and was an overall laggy experience

Is this significantly better on the Vision Pro? If my main reason to buy the Vision Pro is to use my desktop on it ... does that make sense or is that crazy?
