The lack of a manual/quick save option is driving me insane!

I always do a manual save before going into a vault or starting a big battle.  

They're meant to be a long drawn out challenge, not something you can quicksave your way through every other room.

That said, the game does seem to autosave at certain spots anyway. I had no complaints my first time through.

On my second playthrough now, Insanity mode this time. This should be fun.
