Two days ago I posted a
rave about the iPhone earbuds' clickable microphone - and coincidentally, the very next day fellow usability blogger Jasper van Kuijk
posted a rant on the same subject! He makes the very good point that the button is completely hidden - the microphone gives no visual cue that it can be "clicked" - so that many users (himself among them, for a while) don't even know it exists. And it's generally kinda difficult to use a feature you don't know about! Other products' in-line controls look more like the Sony headset in the photo, with "touchpoints" that visually communicate their function. Hmm. To me, this is a case of "design for new users" versus "design for experienced users": the iPhone clickable mic is designed entirely for experienced users (who, once initiated, will appreciate its simplicity and tiny size), sacrificing intuitive discovery for new users (who won't be able to find it without explicit instructions). To me, that logic seems valid: people will own their iPhones for two years, and become "experienced users" in the first week or two. A little pain at the beginning in exchange for years of happy use seems like a fine tradeoff to me!
