I have some 400×240 memory-in-pixel LCDs here that are claimed to do 20 fps at 0.1 mW and some Ambiq Apollo3 subthreshold microcontrollers that are claimed to do 7 ARM MIPS (≈9 Dhrystone MIPS) at 0.2 mW, with the ability to run up to 96 MHz at proportionally higher power consumption. Two such displays would have more pixels than the original Macintosh, and one such microcontroller would have three times its RAM and ten times its CPU power, using 0.4 mW in total. Such a mobile workstation would take 8½ years to chew through 8000 mAh at 3.7 volts, though actually the battery's self-discharge would run it down sooner.
I'm working on a machine built around that hardware, called the Zorzpad, in a form factor similar to the Pocket Reform. My plan for the Zorzpad, though, is to have no battery at all, just solar panels. I think I can get a milliwatt from amorphous solar panels even under indoor lighting, and not having a battery should make the machine last a lot longer: no charging port to break, no battery wear, and no risk of battery fires or leakage.
But the laptop I'm typing this on is about 40'000 Dhrystone MIPS, so it's about 4000 times faster than the 0.4-mW configuration and 350 times faster than the maximum-speed configuration. I suspect the Pocket Reform is closer to my laptop in speed. The laptop has 24-bit color and 2 megapixels; the Zorzpad will have 0.1 megapixels. I think the Pocket Reform has 16-bit color and 1 megapixel.
You will never run Firefox on the Zorzpad, and probably almost no software I run on my laptop will run on the Zorzpad. Most of it will run on the Pocket Reform, but some of it might be slow.
A one-off custom build, but I'm planning to do the physical part with almost full automation, and of course I'll make all my files available under open-source licenses, so it'll be as easy as I can make it for other people to print their own. You might need Google Translate if you don't speak Spanish, though.
