@ravelo I like what your asking for, but the problem is that khadas themselves as from what I have seen put a lot of money into proper R&D and commitment to high quality components that support the SoC used.
To the consumer front this is what is offered, but khadas also supplies to OEMs and ODMs and hence is also able to create more budget restricted devices , but doesn’t for the consumer front so that they can provide a better and robust product.
As for the SoC part which decides a high fraction of the device’s cost, the upcoming rk3566 could have fit your requirements, but at a slightly higher price point, but it seems khadas won’t be working towards bringing that out due to the design of the chip not being preferable
in my opinion we better sit tight and improve what we already have with the VIM3L or VIM3 and make it more supportable to the mainline ecosystem.
Cheers
