[1] The Android code for that test is messed up, and suffers from a race condition and isn't tied to vsync like a normal Android app is. There's a pull request on their github page to fix it, but they haven't accepted it. Regardless, this is a hardware thing not a software one. Apple uses very, very good touch screens. The Nexus 5 also has a really good touch screen, with total touch-to-display latency in the 60ms range.

[4] is total horseshit. He doesn't know squat about any of the platforms. iOS devs also called him out for getting just about everything wrong about how iOS works.

[5] is something iOS devs totally also have to do as well. That is so not an Android-specific thing.
