We recently began testing our doc site (Confluence 4.2.1) on tablets. Most functionality/layouts/etc work fine, with one exception:
On iPad 1 and 3 (didn't have a 2 handy), when the user clicks on a comment box, no keyboard appears. The user cannot add a comment.
A workaround which I figured out is to click on one of the buttons in the comment box's header, and then the cursor appears in the text field.
I assume this has something to do with not having the proper focus, but I was hoping someone might have a programmatic fix.
