Removable battery is cool. Does "quick-swap" mean you can switch the battery while it's operating? I always thought it would be a good idea for devices like this to have a tiny secondary battery or large capacitor in the main unit that would let it keep going for a few seconds while you swap the main battery.
Also curious about this; I'm not much of a tinkerer but I did see their battery has a USB-C port. Is there some efficiency loss in using a spare battery as a power bank rather than actually replacing the battery where it lives?
I would guess that calling it "quick-swap" rather than "hot-swap" probably means no.
