"...the new IE" has been thrown about so much it is basically an empty statement I'm afraid

Safari and Firefox is typically called the new IE because they are lagging behind the times.
Which is why I said "IE6" in my original comment. The later versions of IE were very decent. They certainly didn't seem like the frozen accident of history - an issue Firefox continues to grapple with.
That's a reasonable criticism of Safari, which is updated infrequently and is lagging on all sorts of web standards, but not for Firefox.
