An idea I had for this is a case that would fit two identical phones. Old models that have good Linux support and are cheap - say, the OnePlus 6t. Plenty of performance. One can run Linux (hell, people got Windows x86 running on it, it even runs old AAA games, wow), the other can work as an Android phone. Or both, mix and match, software is up to you. It can work as a mini laptop, dual screen tablet/phone thing (cheapo Galaxy Z?), multi SIM phone, desktop computer (via USB), other use cases. It's niche, you can buy two used phones, arguably more "green" than a new device that needs new hardware, etc. The case itself would have to be high quality, with a custom hinge design, otherwise it would be kinda shit. But it can likely still be smaller and cheaper than PocketReform for example, even if you integrated a battery and USB/HDMI hub. If anyone builds this, I'd love to contribute.
