Funny story about microwaves, theres basically only 2 main manufacturers. They're both in China, and you've never heard of them. But if you look at various brands in the US and take them apart, you'll see the only difference is the interface. The insides are literally the same.

The only exception to this are Panasonic microwaves.

Granted, a microwave with a half broken M1 in it would be awesome.

> The insides are literally the same.

To be fair, is there anything particularly revolutionary that could be done with a microwave (short of "smart" features)? They all function the same: shoot specific frequency energy into the (possibly rotating) chamber. It would make sense that the guts are just a rebadged OEM part.

I'd have guessed that brands would be able to differentiate themselves on even heating, how well the reheating sensors work, etc. But I guess not.

It's not that much revenue because the marginal cost of an individual chip is very low. Given that apple has plenty of silicon capacity, throwing away say 5-10% of chips that come off the line is likely cheaper than trying to build a new product around them or selling them off to some OEM who needs to see a bunch of proprietary info to use them.
