And that is just the easy part. We will also probably need to provide some level of technical support. I am not sure we are in a position to do that at the moment. So the people selling these machines woul have to include a warning about the OS being in beta phase, unfinished and largely unsupported. And really understand this themselves and don’t blame us for it.
As a result, it seems a bit difficult to have the initiative coming from Haiku side. We can’t really approach a manufacturer/reseller and tell them “hey, do you want to use our unfinished OS without any support?”.
Now, if a manufacturer decides that is what they want to do, they have to understand the risks, and probably put the money into it in one way or another (probably hire a developer for some time who can work on writing and testing drivers for their hardware, at the very least).
That being said, you can still try to get a computer with Haiku preinstalled. For example it seems that https://www.thinkpenguin.com has a freeform text input for the OS you want on your machine and so you can try to ask whatever you want. But there is a note next to it asking to contact support first if you want a non-Linux thing (FreeBSD, OpenBSD, or “other popular operating systems”. So, try it and see what they think about it? I think there are other manufacturers or resellers that will accept to test Haiku on a specific machine before they sell it to you, but the testing will probably be nothing more than “it boots on first try without any specific setup to do”.
