For me? I can have a solid, partitioned filesystem like ext4 running on NOR or NAND flash. I don't have a decade to write my own and make it as stable as what's already out there. I can also have the system live-mounting USB flash drives (useful for logging and field upgrades) and reading/writing FAT16/FAT32/NTFS out of the box. If I wanted to tack a SATA drive on there, I can do that too. Oh yeah, and I get a bash shell to manipulate it all on the target device. That's another couple of years saved.
