Consumers dont know what they want, because they are consumers. They just have certian need and think that certain type of devices can fulfill their needs, but at the end, they are not experts. Consumers didnt want a table devices, in fact they rejected many tablet like pc devices with touch/stylus inputs methods much before the iPad, but look now how many of them can imagine their living without their iPads. The same can be said abount the iPhone, the iPod and the Mac. Some 40 years ago who wanted a personal computer in his house? A bunch of tech frickies in the Silicon Valley, and look where are we now. If you leave the consumers to lead your vision about the products of the future, you will stay forever in the stone age. This is how this industry works. Create revolutionaly new products and platforms, build the future based on your own visions and the market will respond positively, it will always will, because even though the consumers are not experts in technology, they have instincts about the great technology in the great product. Thats my opinion.
OK. I am in a forum discussing iPhone screen sizes. Where do I go for an appointment so I can be advised what screen size I want, and why, given that I am a consumer, and that I don't know what I want. Does this also apply to cars, TV, carseats???
