This weekend the 3G mysteriously stopped working on my iPhone, so after months of use, I rebooted it. Rebooting the iPhone takes 1+ minute, and there _is_ a kind of splash screen shown during that time. The reason it appears instantenous during normal use is that it doesn't actually boot or load, it just turns the display back on. Also, many iOS apps actually have splash screens, you just don't see them very often as…
He's talking about smartphone app behavior, not the OS. A lot of good apps (with notable exceptions like Facebook and Kindle) work to minimize the "splash" by throwing up a graphic that looks like the UI, even while the app is loading and the UI (briefly) isn't even responsive to user input. I like it - it definitely smooths the transition into using that app.
