Aren't there countless websites out there with no Flash and only HTML/Javascript/CSS that have atrocious hover-state-based interfaces that are completely unusable on a touch screen device? Why deal with hover-state-based interfaces differently for Flash and non-Flash websites? Is it easier to show a user a mobile version of the site (with no hover-state dependencies) if that site is non-Flash than if it has any Flash on it?
