Why are HTML frames bad?

Question

I know they are, but my co-worker doesn\'t believe me. He keeps telling me that Google crawls the inside content and caches it just fine. According to Google, it does crawl

Depending on what you want to do, most things done with frames can be done with CSS. CSS stylesheets are compatible with all MODERN browsers, meaning your website will look the same if using firefox, chrome, or IE 7(with some tweaks). Also backward-compatibility is not a concern as users can view the content even with CSS off (where as a website using frames and without a frameless version of the site will be useless to a user with an old browser), it just won't be as stylized. It's also quite easy to learn, and once you get the hang of it you'll wonder why you haven't learned it in the first place.
