To be fair, the actual claim was "Apple's apps can replace all but some long-tail usages." which is blatantly false. I'm not an iOS user so I might be a little off - but of your list Apple's apps do Email, chatting (for their protocol anyway), maybe they have a news app? You can do pretty much everything outside the long tail with apps - usually with the better experience (outside of the long tail again) but they're mostly not Apple's apps.
