Discussion of MBA rivals, ie. what the competition is up to. Yeah Samsung are first to 3200x1800, is that news not enough?
With the Samsung ATIV Q you get Haswell, 3200x1800 capacitive touch screen, tablet form factor, Windows 8 Metro and full Desktop and full Android and you get pen input. That's pretty amazing in and of itself.
The dual OS approach, according to Anandtech, Android runs in a VM. There could be issues with high performance gaming in Android mode.
As for resolution:
I don't have a problem with Samsung releasing this hi-res of a laptop. It pushes the industry forward. At least Apple users have had HiDPi for over a year and a lot of the software kinks have been sorted out. All my major apps are pretty much retina aware except Adobe Acrobat.
The issue I have with Windows laptops running this high of a res is scaling. On my 15" Retina, running it full native 2880x1800 is a chore and it strains the eyes if you run it more than 20 minutes.
Running native 1 pixel per pixel display isn't healthy.
Right now, only metro apps can display properly on that screen. They are suppose to fix it in Windows 8.1 but I won't hold my breadth. The solution is bump up the DPI to 200% in windows and it is still sloppy. Case in point. Photoshop. All the toolbars, palette and swatches are the same size regardless of what DPI you run. I've seen demos where people had to use styluses to click on color swatches because they were too small. Java apps and cross platform apps that do not use Windows API will also suffer. None of them adhere to operating system scaling. In short, HiDPI is a mess in Windows right now. So what I am saying is the end-user experience won't be fun unless you stick to metro land.
Let see how Samsung handles interpolation and display resolution scaling.
Right now, I think the Air and Retina separation is good. If you want HiDPI ultraportable, get the 13" retina.

Yawn.
It doesn't run MacOS X. They have to sell it a lot cheaper, especially if it comes with Windows 8. Nobody wants Windows 8. It won't come with Windows 8 Metro, because Microsoft knows they'll lose in court in Germany with that name.
The high dpi model is starting at $1799 according to various sources so not cheap.
