Does anyone know what those panels cost compared to the old ones? Is a 13 inch or a 15 inch panel more likely to show up first? Is a 13 inch panel even feasible? 2880x1800 is seriously crazy, that would be 255 ppi on a 13 inch screen, 50 ppi more than previous commercially available and extremely expensive high-ppi screens (excluding really small screens for phones and the like), like this one: http://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors http://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors Is it even possible to build those panels with the same thinness that they would fit? Oh, and will Ivy Bridge be able to deal with that kind of screen? If not, we can be fairly certain that there will be no Retina MacBook Air. There is just no space for a dedicated GPU on that logic board. Hm, I guess if a Retina iPad is possible (263 ppi, by the way, and that one seems like a certainty) then a 13 inch screen can’t be all that harder. And if the iPad hardware can deal with that screen (presumably while keeping the battery runtime, performance and size the same – I can’t imagine Apple sacrificing any of that) a desktop GPU – even an integrated one – should be able to deal with it, too. The price will be interesting, too. It seems inconceivable that Apple will be able to sell a Retina iPad for $500. The current iPad has an IPS screen and that – the high quality screen with wide viewing angles – is one of its headline features. The next iPad would then also have to have an IPS Panel that is of the same or better quality and also Retina. I’m looking forward to see how Apple will deal with that. (The same applies to the Mac, too.)
