Today the Cupertino based company sent one of its classic invitations for an event scheduled on March 7th at Yerba Buena, San Francisco.

The display seen in the photo is clearly a Retina Display, and almost everyone on the web is discussing about the absence of the Home button. While the first and spontaneous explanation could be that the iPad in the photo is in landscape mode, Gizmodo posted a really interesting article explaining why the iPad in the photo would be, instead, in portrait mode.

We’re just a week away from the revelation and it’s still feels strange that this will be the first keynote about a key hardware product without Steve Jobs.
