Personally I think Microsoft is going to have a harder time convincing users that they really understand the requirement for better security. The perception is that the average user is switching from IE for security not some need for a feature like tabbed browsing. The incremental features come as a bonus for those users that want a more secure system and hence stop using IE.

Put a new front end and some spiffy features into IE and you still have the spyware superhighway.

Prepare for a lot more whining and lying about Open Source software from Redmond.
