Yes of course, it would be nice if a bad batch didn't slow future development to a crawl. Pine64 works in batches, they don't ship promptly, they are also heavily preorder based for in-development projects, and they directly work with developers, as the people who buy them are also the developers of the software which runs on them.

If you get a dead pixel, they will sell you another panel. The laptops are modular, check out how they handled the NVME adapter problems: https://forum.pine64.org/showthread.php?tid=8117

I feel quite confident after seeing their work.

Charging more would make this laptop less accessible to the vast majority of people. The Novena, Talos & many other libre hardware projects were always so expensive as to be botique afterthoughts, rather than "I can spend $100 and get a nice netbook".
