They didn't start at day 1 so here they are.

Wrt scrolling-- could they queue the repaints until the scroll reaches its final destination?

I could live with a phone that reacts "instantly" and scrolls with the animation I expect while showing me transient "placeholder" content.

If you remember early phone browsers, they did the checkerboard scroll thing.

Giving instant feedback to users is crucial. The repaint of content can wait!

The pull down gesture in the video looks like it triggers on touch up. Reminds me of the first gesture handling system I ever wrote. :)

I gave up on it and let someone who knew what they were doing rewrite it from scratch!

Right after the checkerboard (or from the start with Apple) came the rasterized content. That worked (and still works) pretty well.
