Where are they going to source that volume of displays if they move them across all machines? I realize that it does make sense to transition all machines to high-resolution displays; shorting one machine with lower resolution displays would put it at a severe disadvantage. What is the likelihood of this being build-to-order, and not simply a given? I can't see them being able to source and maintain desired margins-especially with larger displays.
Remember that the Macs are not like the iOS devices, they're not going to sell 10 millions per month. They only sell ~ 4 million per quarter (3-4 months) of Macs, so they can get enough panels.
I really don't get it... the Air already has one of the highest PPI counts in the industry. Why would anyone want an even higher resolution display there? The image quality would be more or less the same, but the power consumption and price will be much higher. Apple isn't known for including novelty gimmick features, usually every change they do is functional. The only way I can see them pulling this off is by having soem sort of secret technology nobody knows about which allows them to produce cheap hi-rez panels with ultra low power consumption. Anything else would be a total waste.
They built better battery technologies for the iOS devices that'll go into the Airs. In addition, the laptops will have newer components that have lower power consumption. All can add up to save the battery life for the Retina display.
A lot of people do mostly reading on Airs, those Retina displays make the text extremely sharp, worth it for many people.
However, since you're viewing the laptop further than the iPad, the PPI is not going to go high that much, it could just be an additional 20-30 counts, rather than double the current resolution.
I was thinking this too but just realized that the Macbook Air still needs to support retina for when you hook it up to larger displays. A Macbook Air connected to a retina Cinema Display would be fabulous.
You just need a better GPU to do that, MBA with Retina display has nothing to do with driving an external Retina display. The Ivy Bridge GPUs will be 50% better at the current GPUs in Airs in many areas, it should be able to drive big Retina Displays.
To me the 2011 screens are retina to begin with. 1440x900 resolution on a 13" screen is nuts.
It'll still be 1440x900, just with higher DPI, which means everything would be more clear and sharper but it doesn't become smaller.
But worse, unless Apple have finally sorted out the device independent resolution stuff they put into OSX seeds years back, only to remove it again, and retrofitted it for Lion any higher resolution with the current code, you won't be able to read the screen.
There is no more independent resolution, they're done with that. They're going with Retina/HiDPI instead. Which is double the resolution on the screen itself but show it as the same resolution to users and it is already mostly working in Lion and further improved in ML. HiDPI is much easier than independent solution and thousands of iOS developers already know how to do this from iOS apps, they'll be able to do the same for Mac apps.
