Also you'd benefit security and privacy wise by using GrapheneOS even if you are just an ordinary person. Just because you aren't doing it a special way or getting a device a weird way doesn't make all of it moot. Majority of GrapheneOS users are just ordinary individuals. The security / privacy features protect against a lot of things, like privacy disrespecting apps or targeted exploitation, or excessive data collection from Google.
Discussion
Is GrapheneOS compatible with any specific laptop?
None, but there is a Desktop Mode that is being improved upon. You can mess around with it in developer options. Maybe in the next major releases it will be entirely functional and you can use a laptop style dock.
Open to supporting laptops should the hardware and security baseline requirements get met.
Thank you for the info!!
