   Yep, an important segment.

   NOT everything needs 'cloud' - just a speck of IQ.
   Even 4-bit MPs are often quite adequate.

   For yer crock-pot ... bimetallic thermal 'iq' is
   all it needs ... about 79 cents .....

   People DO seriously over-think the 'basics' these days.

   Hmmm ... look into OS-9 ... an oldie RTOS but still
   being actively developed. Kinda "unix-like". NOT
   "free" however.
