The mere idea of waiting for a kitchen appliance to "boot up" makes me angry. How did we normalize this madness? Telephones, TVs, car engine instruments, HVAC thermostats, why can't any of these be instant-on like in the 80s? Apply power and it starts working is a basic design principle.
Meh. Bootup time is irrelevant if the thing is always on. Many "dumb" microwaves won't let you use them until you set the clock after a power loss which creates an artificial "boot up time" of 5-120 seconds (depending on how complicated the procedure is; I remember microwaves that had absolutely obtuse clock-setting procedures).
