Missing missives

Is the art of letter-writing dead? How long is it since you wrote a letter and sent it off to someone in the post? And is it still "letter-writing" if you type it into a computer? What about if you handwrite it on the screen of your tablet PC? And is the quality of the writing in a letter changed depending on whether it's handwritten or computed? How many drafts/how much editing would you do with a handwritten letter compared with a computer-generated tome? And does it matter - hmmm, can't remember when I last received a letter. I miss them.
