Apple didn’t design the Mac, the iPod, the iPhone, or the iPad because that’s what the market demanded. Most industry analysts said at the time they released those products that they wouldn’t be successful. They didn’t have the key features that similar products had. People didn’t want to be tied to a single application to manage their digital music. People wanted keypads for their smartphones. People didn’t have any use for an oversized PDA. Customers often have no idea what they really want, because what they want may not exist yet. And ordinary people aren’t concerned with imagining completely new innovations. But if you are an entrepreneur or an inventor, don’t always listen to what the market demands. Create and build the kind of business or product that you think can make a difference. One that can provide value, even if no one else can initially see it.
