2 Differences between Tablet PCs and Laptops Computers are more complex, can provide more interfaces, and can support more peripheral devices
Most of the tablet computers use touch operation, and some products use detachable keyboards or slide-out keyboards, which are compact and simple in structure .
2. Weight
The weight of a tablet computer is basically no more than 1 kg, and a 10-inch tablet is between 600 grams and 900 grams. between grams.
Notebooks are rarely less than 1kg, and even netbooks are basically around 1kg.
3. Volume
The tablet computer normally uses a 7-10 inch screen, the overall volume is slightly larger than that of the liquid crystal, and the thickness is not high At 15mm, the thickness of the second-generation tablet products of first-tier brands is mostly controlled within 1 cm.
The thickness of the notebook is basically about 20mm, and the ultra-thin notebook is also more than 15mm. The netbook also uses a 10-inch LCD screen. The number of ordinary notebooks is 14-inch.
4. Input

Security: Windows 8 may be the most secure desktop operating system Microsoft has ever released, but its overall security is still no match for iOS and Android. So far, hackers have been unable to make strong attacks on mobile operating systems.
Disadvantages of Tablet PCs
Because of the space required for the screen rotation mechanism, the “performance to volume” and “performance to weight ratio” of tablet PCs are not as good as those of conventional laptops of the specs.
Tablets are not as powerful as laptops, and pure tablets cannot replace traditional laptops and make it more difficult for users (beginners and experts) to use the computer.
Programming languages are not good for handwriting recognition. Moreover, using the QWERT keyboard layout when entering text requires a person to memorize the letter distribution of the keyboard layout.
The battery is fragile. The battery of a tablet computer is a fragile part, and how to maintain it has become the most troublesome problem for many users.
Typing. Handwriting input is too slow compared to typing speeds of up to 30 to 60 words per minute.
It takes a long time to lower the head when using the tablet computer (when there is no dedicated base), which will cause certain damage to the user’s cervical spine, such as neck pain and stiffness.
4 Classification of Tablet PCs
Dual-touch type
Definition of dual-touch tablet PC Finger touch and electromagnetic pen touch” tablet. To put it simply, IPAD only supports capacitive finger touch, but does not support electromagnetic pen touch, and cannot realize original handwriting input, so the business performance is relatively insufficient. Electromagnetic pen touch is mainly to solve the original handwriting.
Slide type
The advantage of a slide-type tablet is that it has a full keyboard, while saving space for easy portability. It fits together like a candy bar tablet, and can be flipped after the slide is pushed out. Its obvious advantage is that it is easy to operate. In addition to handwriting and touch input, it can also be input by keyboard like a notebook. The input speed is fast, and it is especially suitable for entering account numbers and passwords when trading stocks and online banking.
Pure tablet type

5 Tablet PC Screen Material Selection
For touch screen tablet PCs on the market, there are generally three types of mainstream display screens used in tablet PCs: IPS screen, MVA screen and TN screen. Among the three types of screens, the IPS screen is favored by mid-to-high-end products due to its high brightness, bright colors, and a viewing angle of up to 178°, but due to its technical limitations, the power consumption is relatively large, and low-end products have light leakage. Most of the current mid-range and above tablets use ips screen solutions.
Screen size
The mainstream tablet size can be divided into 10 inches (9 inches, 9.7 inches, 10.1 inches and other similar sizes) and 7 inches. A 10-inch tablet is generally suitable for home entertainment or when there is a support, and the weight of the whole machine is relatively heavy. The 7-inch notebook is now gradually becoming the main force of the tablet. The reason lies in the lighter weight and decently sized screen. 9.7 inches (iPad) is 4:3 ratio, suitable for games and entertainment.
Hardware configuration
The parameters of CPU, GPU and memory will be related to whether your tablet can run 3D games smoothly, or you can only browse the web and browse the forum. Generally speaking, the higher the parameter, the better the hardware configuration. In this regard, you can decide according to the actual needs of the purchase. But as mentioned earlier, all aspects should be considered comprehensively when purchasing a tablet computer, and you cannot just ignore the configuration and ignore others.
Battery life
This parameter is very important. There is no doubt that the longer the battery life, the better. Especially when you’re out and about, it can be frustrating to suddenly run out of power on your tablet. It is best to have more than 5 hours. ARM has low power consumption, so it is not difficult to meet this requirement. For less than 2 hours, resolutely do not consider.
