I've read somewhere that for BeOS demos they used to play a bunch of videos and music and then unplug/plug and after boot everything was playing again from where it left. I guess they were using the same design for process persistence.

That was just the media player remembering where it left off and restarting from that place. There may have been some metadata support in Be's filesystem to help that, but it's not technically necessary. It's about as amazing as your web browser reloading your tabs when you restart it.

If "never loose data" isn't a great selling point then I don't really know what is.

It's a trivial problem if you're willing to run your system entirely off of the disk. I mean the performance will be unbearably slow, but you'll never lose your data.
