You hold a smartphone a foot away from your face. That’s why a “Retina Display” at 1 foot away has to be >300 PPI. But few of us hold the iPad a foot from our face. In fact, Steve Jobs made a point of showing it being used in his lap at the iPad intro event. That’s 2-3 feet from your eyes. At 2 feet away, “retina” becomes somewhere between 150 PPI see chart (via) below.
iPad is currently at 132 PPI which would be pretty close to “Retina” at a little over two feet away. The current Macbook Air is 11.6″ (Widescreen) 1366×768 is 135 PPI by comparison. Doubling the screen resolution to 2048×1576 would put the screen resolution way into the invisible range at 2 feet. That doesn’t make a lot of sense, does it?
Perhaps I’m wrong on the 2 feet thing? Does anyone use the iPad at 1 foot from eyes?
Update: A lot of commenters are 1 footers. Who knew?
