OK ignoring who said what , when and how wrong they were the answer to O.P. is 
on the yaffs web site in the middle of the first page.

>>
YAFFS is useful for NAND and NOR Flash
It provides Wear Levelling
It boots quickly

Error Correction makes it robust under power failure

The RAM footprint is small
It now handles larger page sizes of 2KB
MLC NAND handling is under way
It has ongoing development

It's especially designed for flash devices and embedded systems. It is very 
robust to power failure. That's why TS use it I imagine.

That's not to say you won't lose unsaved data but you should not end up with a 
srewed up fs and a boot failure.
