This is bordering on off-topic to this list, but, the ARM64 architecture is becoming more useful:
An RK3399 laptop with * magnesium chassi, * M.2 PCIe NVMe SSD slot (four-lane PCIe v3) and * 4K@60hz displayport output, * full HD IPS display, for 200 USD is coming to market. Keyboard layout may be UK/ISO. Its hardest functionality limit then should be the CPU/SoC's 4GB RAM cap. https://liliputing.com/2019/01/pinebook-pro-linux-laptop-coming-this-year-for-199-and-up.html https://www.omgubuntu.co.uk/2019/01/pinebook-pro-linux-laptop-coming-soon https://www.forbes.com/sites/jasonevangelho/2019/01/30/the-new-pinebook-pro-will-challenge-google-chromebooks-for-199/ And they're making an Allwinner A64 smartphone. Both these SoC:s are supported by OpenBSD. Some day these devices will break through their 4GB RAM cap, and some day they'll become faster. And some day RISCV will take the steps ARM64 is taking now. This is great heterogenicity progress. Tinker
