The problem is that there are very few devices with flash memory which are older than 30 years. Affordable flash memory for the consumer market only came about during the early 1990ies. So there will not yet be enough data to verify that 30year lifespan claim.

The oldest device with an operating system on flash memory in our household must be the washing machine from ca. 1995. But this does not count because it got it's water level sensor replaced about 10 years ago and the technician took the opportunity and updated or reflashed the ROM. So it now has another 20 years to run :-)
