Posting the form to an iframe is by no means the same thing. Posting the form to an iframe:

1. Requires the user to click the submit button.

2. Does not update on every keystroke.

3. Requires you to use an iframe, which is not a valid element in XHTML Strict.

Of course, posting the form to an iframe might be an acceptable solution in many cases, but it certainly does not offer what AJAX does.
