Personally, I think it's a useless feature. I've always considered the 'Send' button to be like dropping a letter into a Post Office box. Any edits that I need to make or attachments I forgot to attach would just mean to me, "Oh darn, send another email", and these changes if needed I wouldn't think of in 15 seconds anyway. Someone once said 'as you age, your memory is one of the first things to go', I think, but I don't remember who it was or where I heard it..
