More on Resolution Independence

Ive been playing with this for the past few days now and it really is very smart.
If you simply leave all settings as standard, and design for 320x480 and leave the engine to 'scale' the app up for retina displays what happens is all fonts, vectors and graphic effects seem to be automatically doubled in size (as opposed to scaled up), while if images are referenced on the 320x480 display the standard image is displayed, while on retina the @2x version is shown.
Two really easy ways to see the results are.
a) put something different in the @2x images to show it is being used on a retina display or simulator.
b) compile the same app using LC6.5 and LC 6.1, you can clearly see the difference in resolution and quality, it is more than simply scaling as the fonts are all crisp, vectors perfect and images are not just scaled up, they are swapped for higher res versions.
It does look like a really good solution, especially as it makes developing retina apps on a standard resolution display much easier!
Its just getting your head round the fact the screen is the same size so the design should be the same for both standard and non retina, its just the images that need to be a higher quality for the higher quality displays and the engine takes care of everything else automatically.
