Universal apps that have @2X artwork are already ready, don’t even need to be recompiled
UIImageViews scale using bicubic, not “nearest neighbor”, so images on websites won’t be blocky
Unlike last time, the SDK you have now already supports Retina so things like UIToolBars should already be ready to go (unless you customize with your own graphics)
If a website already makes @2X calls or uses larger images scaled down, it’s already ready.
Auto Adjust includes @2X artwork. I bet I won’t have to do an “iPad 3 compatible” upgrade *for Retina purposes. There may be some new feature I want to implement.
There is exactly one thing apps NEED to do: Provide a 144×144 (72@2X) icon (if Apple doesn’t just grab the 512×512 iTunes copy and scale).
