The best example of this is the Galaxy line of Samsung phones. Most people, myself included, didn't think that these very large-screened phones would sell very well. People want smaller, leaner phones, I thought, phones that will fit in their pockets easily. The Galaxy line has been getting increasingly larger, however, and selling better with each generation. And the Galaxy Note phones are huge for phones, being very much like small tablets, with a stylus and all. But the markets liked these ideas, and Samsung is getting better at marketing them. And so the direction of smartphones has changed, and the desires of consumers are changing. Samsung is either guiding this, in part, or following the will of the public. Either way, Apple is failing to do so, and their iPhones have changed very little in the past few years, remaining almost the same phones, just with better hardware. And they don't seem to know what to do when they are not trendsetting.
