they'll be rolling the dice even past this date (but had they not got used to?). MS defense for IE will address only known threats, noscript is much more flexible tool. on the bright side - XSS filter is dumbed down/automated tool for masses.
but why would anyone still use IE if this thing is no longer necessary even for windows update - masochism?

To learn that you're promised potection in June from what Firefox noscript users have been for at least two years now. You roll the dice on every site you visit until then.
