Yes, I can relate to that, well you have on the RISC-V something to buy now, the MILK V, from my last post.
On the x86 side, not too sure if there will be a clone on RPi Module clone on x86, or a SO-DIMM on the architecture (I could be wrong here), also the battery would just be drained fairly quick, unless you’re ok having the USB plugged all the time during usage.
Either way, yes we need more power to play around either RISC-V, ARM or X86
