"every day, your cursor protects you from unclear UI. It helpfully
turns into a text cursor as you hover over textboxes, or a hand
as you hover over a link or action item. iPad has no such thing.
Bad UI will stick out like a sore thumb, both in apps and on
websites. Your tappable areas had better look tappable. Your
controls had better look controllable. That decorative little
page-curl in the corner of that entry had better turn a page.
Without being able to subconsciously hover-to-test, users will
end up frustrated at anything that doesn’t do what it looks like
it should do, or vice-versa"
