Here's what the invitation to participate in the iPad 3 tablet presentation event really says

iPad 3 - image analysis of the presentation event

  Although the image sent by Apple along with invitation to attend the iPad 3 launch event clearly denotes that the device it will have Retina Display, she still questions the existence of the Home button. These are the only two important details provided by the image, but those from cultofmac they wanted to make a complex analysis of it and see above the meanings of all the details included in the picture. Some of them are comical, but some of them could have something to do with reality.

  Moving on to a second interpretation of the image, those from CulofMac see the hand positioning the hand above the tablet as representing a graph of the number of Macs sold by Apple until the launch of the iPad tablets, and of course this is just a simple parody.
