This video of the “iPad Head Girl” walking around New York City is a new viral marketing campaign from Hearst, the company behind the new Cosmo For Guys publication that launches today on the iPad. Her expensive headwear features four iPads that show her head from different angles. But the best thing about this pricey hat is that when you’ve finished looking at her face, you can read her like a book. (Or magazine.)

One of the biggest changes that Apple has implemented in Mac OS X Lion is Mail version 5.0. The new version of Mail has a whole new look and feel to it that I’ve heard a few of you complain about.
