4 GB RAM limit

[Arwen]

I needs 8GB. It's not enough ram.

Then the Pinebook Pro is not, (yet?), suitable for you. And won't likely be for at least 1 year, probably 2 years.

It's possible in a year or 2, a new SoC can be used for a new Pine64 laptop, (Pinebook Pro II?), that would support more memory. But, there is nothing that can be done today.

Another vendor might have what you are looking for, (I hear people are working on getting Linux running on Apple M1 laptops).
