I've been banging on that drum for years, and the first time I posted on the Haiku forums people said it was proprietary and wasn't going anywhere, and that RISC-V would be a better priority.

Fast forward some five or six years and there are literally _hundreds_ of ARM SBCs out there that could be running Haiku instead of hacked Debian.

I would answer them Raspberry Pi is the only standardized-config, also fairly widespread and reasonably affordable computer. Standardized config is a must for a custom OS (so it is reasonably easy to fully support the hardware), price is among things which killed Be, vibrant community of geeky enthusiasts of all levels is a great bonus. RISC-V doesn't have any of these, it hardly even exists.

This was a few years back, and yes, it was already obvious it was getting mass produced and taking off. They just didn’t care up until the 3B+ came out.

Haiku has (experimental) support for Armv7 (or later). Would a Pi not meet this requirement?
