passwords

Thanks a lot Apple iTunes!
You made me change my password today. Which I did. Only, you wouldn't accept any of my usual passwords. Apparently, a real word (no matter how vague it is) isn't allowed. I had to make up a word. A word that you won't find in any dictionary. And then I had to add a bunch of numbers and characters to it as well. It was the only way you would allow me to save my new password. So now, not only will others never be able to guess what my password is, I will never remember it either. Unless I write it down somewhere. And just how secure is that?
