In general isn't that the way it's been always?
That is correct. What is different about this situation is that the bad guys are waiting to launch their attacks and there is no support from Microsoft. If an OS update us required to remediate the attack, many users are hosed. Their fix is to move to a new OS after the attack. A lack of support from Microsoft also effects the anti-virus companies. With that said, I am not super concerned with migrating home users. In the business world there are different issues; some not even security related. For instance, the cost to support a single desktop platform vs. multiple desktop platforms.
