As a duel user I can say that for me I would much rather work in windows but play in Mac. Office is more responsive in Windows, snapping windows is great, the red close button is more convenient, Windows has no stupid rubber-banding and functions like save as and end of document are better than OSX offers.
On the other hand Windows really has a problem with its non-consumer- friendly OS configuring, the lack of a real, integrated full system backup and terrible, terrible system rebuilding from scratch.
Additionally Windows lacks the beautifully well done mail, music, calendar, contact and pictures apps that have become of the heart of the Mac experience. Some of the Windows Essentials apps are OK but not even close to their equivalents on a Mac. The Metro ones are an embarrassment.
As they have pointed out Microsoft is trying to woo back, or retain business users. Unfortunately I heard nothing that might address home or casual users. Unless users can pick up their new laptop at Best Buy and immediately sit down and start doing real stuff (like you can on a Mac) there is not a lot of draw for Windows.
