er no. iPad is broken. If apple provides a platform that doesn't respect standards and disallows other browsers from working as they're intended to, it does not mean the entire world that does not feel like supporting the walled garden is broken.
It's a colloquialism referring to a users broken expectations. If a user tries to open a page and it doesn't render properly, the user will blame the page, not the device. If a website renders wrong, that's the websites problem.
If the site uses a feature that is unsupported (or poorly supported) by a browser with significant market share, then its the sites responsibility to fail gracefully. You can rant until you're blue in the face about how the iPad/Safari should handle these things better, but most users simply don't care about your particular definition of "broken". They only know the site doesn't work.
