The only times I miss Flash on the iPhone are when I hit a website where the web designer hasn't done the due dilligence of making sure their web site still works without Flash.

I have more than once wanted to see a restaurant's menu on the iPhone, and couldn't, for this very reason.

I know, it's the web designer who needs a smack upside the head in this situation. But since I can't usually administer such penalties in person, the only remaining option is to put the darn Flash on the iPhone. As awful as that is.
