First, what poor design choices did they make? The entire post was attempting to debunk the perception that there was some simple decision that leads to the issues people describe. Second, I don't believe Dianne has a fundamental misunderstanding of anything regarding a mobile OS as she is one of the most preeminent people in the field. Its frustrating and annoying to read posts like this where you try to walk a "I'm impartial" line and then pepper it with biased remarks that are misleading. You are unlikely to get more factual discussion about the situation then the post she offered, as she's a creditable expert who has written a not insignificant portion of the OS under discussion. Its clear that iOS has some really technical achievement they should be proud of, but your desire for facts about the situation is subverted by your very own use of statements like "drawing/compositing in iOS on a 3GS is faster and smoother than on a shiny new Android Inspiration XL HD 4G" without anything to support your position. Its not a fact because you make a statement.

Well, she does (have a fundamental misunderstanding of something regarding a mobile OS): she is an Android developer, and it is pretty clear from this article that she has no clue what she is talking about when it comes to iOS. Seriously: you should trust Xuzz from this thread much more than Dianne about issues related to iOS surface compositing. Xuzz worked on jailbreakme with comex, did much of the work for the recent Siri-on-non-iPhone-4S ports, and has written numerous modifications to the code of SpringBoard (the main window manager and graphical shell process on iOS) over the last few years he has spent reverse engineering that system, and most of his posts on this thread are corrections to statements that Dianne seems to have simply made up for this article of hers. (For "people to watch" on this thread, I should also point out ryanpetrich, who is responsible for such modifications as DisplayRecorder (which records the iOS framebuffer to a video file) and DisplayOut (which splits the framebuffer out to a television), both available for jailbroken devices.)
