What do a short attention span have to do with it? It's a necessary evil to have a password on your phone and not only is touch ID more secure, but it's faster and easier. Congrats on being the first person to complain about that combo.
How many people (I am certainly one) skipped on replacing their original/iPad 2 with a new one this past year because of the lack of Touch ID? If my next phone is going to have it then I want it on my iPad too. I can't imagine I was alone on that.
