I largely don't see it as this anymore. Especially with games with not so good saving. Between my job and personal life I often have to drop what I'm doing at a moment's notice. Using traditional saving that means I lose a huge amount of progress. But with save states I lose nothing. Replaying some old DS games by emulating has been much better with save states.
As many others have said, it's also great with games that are unfairly difficult with poorly made save systems such as Zelda 2.
