I use my iPod Touch a lot at home and can read the site just fine using the web browser. But when I click to type in a text box, nothing happens. It just flashes like its going to zoom and let me type, but it doesn't.
Not sure how you could test that if you didn't have one, but I wouldn't hurry as it seems no one else has a problem with it, and it does keep me from spending all of my time here. :-)
