While I am fan for all the extra nerdy stuff, especially the cellular connectivity, but I doubt the battery endurance will be impressive, my current zero lasts weeks on a single charge. This is more of rpi plus addons in one package, great, but until we get to know the heat and battery life.

They mention in the comments intending to have modes that solely run on the microcontroller, so I imagine that might help somewhat.

This also feels like the target market is people who said they dangled this off an RPi-alike to do something that the microcontroller simply did not have the processing to do.
