I had also assumed atob('string literal') was being pretokenized into a binary-safe format that doesn't need escaping, since that would be smaller/faster. It would allow displaying graphics without taking up RAM... but would it be just as fast, or is external flash slower to access?

atob() is function call, makes new buffer in RAM when called, yes external flash is slower, every byte from SPI flash is read by toggling GPIOs in software, it is fast but much slower than internal RAM/Flash

Yes, but so is E.compiledC. In the same way that compiledC is replaced, so can an atob call.

It's bit bangging SPI? o_O

Yes, but so is E.inlinedC. In the same way that inlinedC is replaced, so can an atob call.

It is not tokenized but with direct string constants it could be, good idea.

Espruino is single threaded so using hardware SPI may not help much and may actually draw more power. We don't know for sure until it gets implemented :-)
