How simple can auto-save be to implement? I just lost about 3 paragraphs due to Apple's "Pages" application (their alternative to MS Word) crash. I know that's not a lot, but it's the principal that counts. It makes sense to have some kind of recovery feature or auto-save. People don't use word processors as a joke and enter text that they're hoping to lose because of your application crashing.
There's a free no-thrills text editor on OS X called TextEdit and this has the ability to save every x seconds which incidentally is free of charge whereas Pages costs $80.
It doesn't make sense to me.
