But with a locked bootloader, so not necessarily
Why the specific ISA desire?
(Hate UEFI all you want, but standardizing on something is much better than the Android world where every SoC requires a custom bootloader and if the manufacturer doesn't support the kernel you want to run, tough. Having a standardized platform to run on means you can have a Linux distribution that supports running on any device that supports the standard.)
But I do use it as a production machine.
Traditionally, one of the ways people got into Linux was inheriting an old box and sticking Linux on it. You won't be able to do this anymore.
And as Intel will become more and more niche, it will get more expensive.
