Yet another killed Vista-Feature

With Two-Factor-Authentcation removed from the Vista-Release yet another feature was killed. But when each interesting feature in won´t make it in Vista, the rationale of migrating to Vista is more than questionable. Why should someone migrate from XP to Vista? Only for a nicer GUI with more bells&wistles? An operating system with new bugs, new security holes, a new interface, but without any real advantage. From my point of view Vista will be the biggest flop since the construction of the tower at Babel.
