For the laptop, you can use an HDMI capture card and OBS to use it as a second monitor. Keep in mind though that it’ll only support the resolutions that the card supports so depending on the card you may be limited to only 4k or 1080p resolutions.

I remember my high school teacher once said he’d want to try a Dodo Bird if it can be brought back to life lol

I prefer Brave’s interface over Safari on iOS even if they both use the same engine. I like how Brave has the scrollable tabs in portrait mode and the search button on the bottom so I don’t need to reach over. Also it syncs well with my laptops which I use Brave on too.
