1. The wrist is a valuable place to wear accessories. However, the current "watch" is no longer the original watch. Most current smart watches are fashionable products, basically all are black cubes. Even if the shape changes and the colors are diverse, they are far less beautiful than the original watch.

2. It is necessary to make smart watches of many sizes. The sizes of watches worn by men and women are different. Moreover, everyone's wrist shape is different, and the size of the watch they carry is ever-changing. How many sizes of smart watches can manufacturers manufacture now?

3. Poor user interface is a problem. Obviously, the screen of a smart watch is very small. Running some application software on such a small screen, mistakes and unpleasantness of various operations cannot be avoided.

4. The case will increase the size of the smart watch. To avoid this problem, manufacturers have tried to make the size of the watch as large as the screen. Allegedly, iWatch and Samsung and Microsoft smart watches are only 1.5 inches in size, but this size is not suitable for wearing on the wrist all day.

5. The battery usage time will also cause restrictions. Sadly, the size of a smart watch is too large for the wrist, but the size of its battery limits its capacity. The battery of a smartphone can only be used for one day. You just wait to charge your smartwatch several times a day.

6. Typing will be very unpleasant. Imagine, on such a small touch keyboard, are you ready to type with the tip of your nails?

7. Unless the voice input technology is perfected, this problem will not be solved.

8. The appearance of smart watches is ugly. "Large" is a feature required for smart watches, but the large size is ugly to wear. Now, even the best-designed iWatch looks a little ugly, and the e-ink just launched is no better.

9. Apple has already released similar products. If you add a strap to iPod nano, it will be no different from the smart watches on the market now, whether it is compared in appearance or function. Because of this, after the first nano was released by Apple, it began to chisel the strap groove on the next nano. In fact, smart watches appeared as early as the 1980s. It's just that smart watches have never been easy to use. Now, who will use those products, just like no one will use the first generation of Apple. There is no guarantee that smart watches will become popular in the future, but for now, smart watches will have a long period of sluggishness.

10. The price of smart watches is too expensive. Listen, are you willing to spend 150 US dollars (about 930 yuan) to buy a small electronic product that is neither fancy nor useful? Sony's smart watch is at this price, and all of its functions are available in your current mobile phone.

11. The update will be soon. The product update cycle is fast. Generally speaking, a person using a mobile phone or tablet will not exceed three years at most, because then the battery is almost degraded. Therefore, the replacement of smart watches will be more frequent and more and more money will be spent.

12. Need to support a lot of data. If the smart watch will only connect to Wi-Fi, it will be useless. Because, in the case of Wi-Fi, users are the first choice to play their own mobile phone or tablet. So the smart watch needs another device to support its data, or it simply uses Bluetooth connection.

13. Blurred positioning. Is a smart watch a tracker or a simplified smartphone? If it is the former, will this product be accepted by the public? I think most people do n’t want to be followed by others. If the latter, is it a bit redundant? Isn't it enough for the average person to have a smartphone? If it is a combination of the two? Do we choose leather straps or rubber straps? So tangled!

14. The situation is very similar to 3D TV. Whether it is a smart watch or a 3D TV, it sounds like a gimmick, but most consumers have no clear demand for these. And the companies behind these products can't think of a good idea to enhance the functionality of the products, so it is really tasteless.

15. The Supreme Detective (character in the movie of the same name) will not use a smart watch. A smart watch may be reminiscent of the once-popular Supreme Detective, because he used a watch-shaped mobile phone in the movie. But if he lives now, he will not use a smart watch, but the iPhone, because the iPhone is better than the smart watch in every way. Therefore, if you want to imitate the Supreme Detective, a little innovation will be better.
