My browser can type my credit card information faster than I can.

Honestly, `autocomplete=off` is an unwelcome attempt to try to save me from myself.

I always thought of `autocomplete=off` to guard shared computers. I've turned it off for CC fields but the intention is that if you're on a shared computer the security outweighs the browser remembering something such as a credit card number.

I don't believe people type values into a form realizing at the moment that the browser is saving it for future uses.

They intend for that to be stored. http://www.chromium.org/developers/using-requestautocomplete

The change that they're making to Chrome only affects password fields.

+1 and even more importantly CVV fields.
