Cocoa Newbie: What are the differences between Core Animation on Mac OS X and Cocoa Touch?
One biggie (for now at least), is that on iPhoneOS, Core Animation does not include filter-based animation.
On the other hand, Core Animation is more naturally integrated in Cocoa Touch than in MacOS X's Cocoa. E.g., view transitions can implicitly be animated (no need to change source to use a special property field).
