Although the contradiction is still legendary

Simple and complex.

When I first touched the BlackBerry, I faced a complex machine with 26-letter keys and other auxiliary keys, and there were three different ways to open a program. But it also has a key to open the program's convenience, there are perfect program background switch and fluent text input experience.

I've recommended blackberries to a lot of people, but I've rarely been successful, and when the iphone is getting better, I've recommended the iphone, but I've seldom failed. As far as I can see, the main reason for this is the impression: Because the BlackBerry is too complex, the iphone is intuitive and straightforward.

There was only one way to open the iphone, and there was only one way out. Just touch open and then the home key exits. And the home key is the real entity key, requires the user to press, so there is a real matter of elasticity rather than vibration simulation. This is a real switch, and it also means the ultimate control over the software. It is precisely this ultimate control that gives a sense of reassurance that many people may not know how the iphone works, but they can stop everything and start over at any time. Technically, the iPhone is a more complex machine than the BlackBerry, but it has the simplest ultimate control. One of the ideas that the IPhone has won is that it presents complex technologies in simple forms.

The features that we see on the iphone, the icons that simulate reality and the design of the interface (the idea is more extreme in Apple's own software, such as podcast,ibooks, memos), and home keys are all from the idea of making the iphone "simpler to use", The IPhone did. What Apple does, however, is innovation rather than innovation: packaging the most physical buttons of the past into touch-screen buttons, and the ultimate control is in the home key, and the Apple does not have the Subversion button, but instead the form of the button.

Simplicity is not the true nature of technology, and when Apple began to really face multitasking, Apple found itself having to salute and learn from its predecessors and peers, IOS4. Today's iOS5, counting on the notification system, there are three ways to open the program. Exit is also more complex, after pressing the home key, you also need to double-click the home button, long press icon, and so on after shaking, and then touch Cancel. It's a lot more complicated than just pressing the home key to exit.

Simplicity is simple because it does not do complex functions.

This is the price to pay for multitasking, which is the price of the simplicity of the final control for the home key.

Complex and simple.

IOS is not without a real multitasking solution, and a variety of gesture plug-ins can achieve easy multitasking complex operations, which is a complete revolution of the button. But in this way, the learning cost of the iphone will also be greatly improved, leaving the simple logic of the home key, the iphone will become abstract and complex to use. Leaving the final control of the physical button, users will be completely dependent on the touch screen when they use it. In the event of a system problem, users cannot even use the ultimate solution to unplug batteries like other branded handsets.

Compared with gestures, the "slide" operation can be a more moderate transition operation, the "sliding" operation of the key word is "hidden", the button is not out of thin air, but is hidden in the content next to or under the content, a little drag can be found, visually more intuitive. From the operation, the sliding operation does not need to be repeated back and forth between the buttons, and the operation is more convenient and fluent.

The only cost is the early learning, "sliding" is "hidden", need to tell the user in advance, more difficult to find than the function of the home key. But this study is valuable, in the familiar, you can leave the home key multitasking operations brought about by the rush.

The way of learning is the cost of multitasking, which is the cost of driving a simple, intuitive home key out of the operation.

But for multitasking and complex operations, the IPhone will have to be complicated, like a BlackBerry five years ago. Interestingly, five years later the BlackBerry, now completely abandoned the physical button, thoroughly turned to the "sliding" operation.

In the face of all this, Apple will not be indifferent.

It's a contradiction, a legend.

Jobs talked about the iphone design with the idea that he doesn't like buttons, like in life, and doesn't need one thing, and when it does, everything stops.

Interestingly, the home button on the IPhone is the ultimate control button because the button is simpler because the button is more intuitive because the button doesn't need to be learned.

This is a paradox, along with all the other contradictions about jobs, to inspire, to become a force field, to be legendary.
