Hi there, writer of that long article! 
Love your work, look forward to seeing more of your exploration of the PineTime... means I can learn more about them while I wait for GA of the Dev kits.
The breakdown of FLASH memory usage... looks quite reasonable, considering the current state of development. And as you said, there's still that SPI Flash that assets such as fonts, graphics, even apps, can be offloaded to.
The MCUboot mechanism sounds very much like the eboot one used on the ESP8266/ESP32... i.e. allowing OTA updates via multiple application slots.
Anyway, nice to see you on the forum!
