Except you're nowhere close to reality.
pre-JellyBean:
swipe animation queues all 30 frames of the swipe animation, does NOT drop any, and struggles to complete them all, taking 4 seconds to walk the queue with as many skips and pops as expected. Video Player fail.
JellyBean:
swipe animation probably does not queue 30 frames of animation, but ALSO gets PRIORITY to COMPLETE them first in the allotted 1 second. Video Player success
Real-world example, keyboard response -- which is more responsive?: the console that reacts instantly to your key-presses even under a load of 24.00 on a single-processor, or a console that gets back to you after it's done processing some background tasks. The former is "actually" and "feels" more responsive, while the later will run the bg-tasks slightly faster.
