scrollbar not showing up for the following textbox on the iPad when I fill it with text.
<textarea type="text" name="holyCow" rows="30" cols="120"></textarea></p>
Mobile Safari doesn't show scrollbars (except the temporary one when you're scroll the entire page). Older versions of iOS require a two-finger drag to scroll interior elements, newer versions use a normal one-finger drag.
If you really need (or want) a scrollbar for the iPad, I've had reasonable success with TouchScroll but I don't know if you can add that to a <textarea>.
