I've tried SRS's and don't like them. They're only good for memorization, and if you're memorizing something that you need to use, using it is a -lot- better than using an SRS.
Plus, memorizing complex things with via SRS isn't easy. Figuring out how to break down the cards into small enough pieces is really hard for any non-trivial information.
For instance, I tried to use it to study for the PHP Cert from Zend. I passed the test, but only because I spent so much time researching to make the cards. The actual studying of the cards was pretty much useless after having done the real work of making the cards.
I tried to use it for studying languages, but I've found that the time making the cards is pretty much wasted (it's copy and paste, no thought involved) and studying them beyond the first few reps is pointless, too. If I can get through a few reps, and I'm actively using the language, there's no need to continue doing reps beyond that. I'm better off letting someone else make the list, study them like normal flashcards a few times, and then throw them away. (Better yet is something like iKnow that has the word, translation, picture and sentence.)
In the end, I've never actually found a use case for an SRS system that wasn't trumped by something else either because of easiness or just being better.
