A nice Windows 8 ad after a long time:
A single student using a Lenovo Yoga amidst a sea of initially mocking iPad users. But when the professor asks for the students to take out the book and take notes at the same time, only that Windows 8-using student is ready and can do two things at once. The iPad users fumble with their silly third-party keyboard attachments (and in one humorous case ham-handedly try to type right on the screen).
And then an iPad-toting fellow student Skypes the Windows 8 user and asks for her notes.
