I love Edie! Edith is OK, but I'd only use it so that I could use Edie as a nickname.My great-great Aunt was called Edie, her brother and sisters were Reg (Reginald) and May.
That's how I feel... I get called "Edie" fairly often even though my name isn't Edith, and I really love it. Unfortunately, it's hard to find a more aesthetic full first name to allow for it as a middle name :(
