I'm not a Windows user so maybe I'm way off, but wouldn't adding Cortana go much farther in getting people to upgrade?
How's the Kinect support in Windows? Quite honestly, Microsoft is only competing against itself. How many XP uses are still out there? A couple hundred couple hundred million? Give them a reason to get excited.
It seems like you haven't paid much attention to the leaks and rumors out there... Cortana is 100% going to be in Windows 10 from the looks of it. Also, this package manager is designed to get the people MS needs excited the most - hardcore power users like us.
This isn't aimed at consumers. This is aimed squarely at businesses. Cortana won't excite them as much as further automation which decreases workload and by extension costs.
