If you already have a NAS, (since SMB was mentioned, I’m assuming there’s some sort of NAS setup going) then you may even be able to host Plex directly on the NAS. It likely won’t be powerful enough for things like video transcoding, but just audio should be fine.
This is actually backwards. Texas Instruments made so many bomb chips that they ended up with a surplus. This allowed them to throw those chips into calculators and edge out any competition with lower prices (because they already made the chips, so they weren’t paying for them.) Then once they had run off all the competition, they jacked their prices up.
And that, kids, is why the TI-84 costs $100. It’s tech that costs all of $10 to make and program.
