My iPhone usability peeve is the lack of an authoritative, comprehensive reference manual. I know lots of intelligent people who lack “technical affinity” but are nevertheless perfectly capable of reading. The iPhone gets a lot right in terms of discoverability and usability of 90% of its functionality, but that last 10% is frustratingly hard to find definitive answers for. There’s also a further 10%: The functionality you think the iPhone might or should have, but doesn’t. Good luck getting any official source to confirm though. You are left to trawl helpless forums.
