Not many people do this (I do, and have done for many years) because they're too used to unreliable systems. A solid (likely *nix-based) system with a UPS and some sort of a backup/save to non-volatile storage on long power-outage strategy works so well that the risks are well worth living with (on the occasions I've blown it, it's generally been some sudo-related thoughtlessness). Edit: the one thing I'd like from a ram disk for it to survive a reboot; poking about, most memory contents doesn't change across a reboot but AFAIK no OS has the ability to persist a RAMdisk across a restart.
