Even in the hands of schoolchildren, tablet computers can often be seen now. It all started with the famous iPad - it was Apple that largely contributed to the emergence and development of the “tablet boom”. Over time, dozens of other manufacturers picked up this trend and began to produce similar devices with a variety of characteristics and design. Let's figure out why tablets are needed, and whether you personally need such a gadget.

Before you go to the store for such a coveted and actively advertised equipment, you should decide what exactly you want to get in the end. For example, many people see in the tablet a more advanced and functional replacement for electronic “readers” for books. Given that paper book prices are rising from year to year, and not everyone wants to carry heavy volumes everywhere, this really becomes one of the answers to the question of what tablets are for. However, are they really that convenient for this purpose? In practice, a tablet, in which, in addition to applications for reading books, there are many other functions (for example, the ability to simultaneously reply to someone reading VKontakte or copy a quote you like on Twitter), does not contribute to a calm, measured reading. The user’s attention constantly switches from one task to another, as a result, to fully enjoy a good book and to carefully consider the text still does not work.
But in terms of games, tablets definitely benefit compared to the same smartphones and even netbooks. Already, many exciting games of different genres are adapted for touch screens with a large diagonal.

As for music and video, here, it would seem, there are no problems. They can arise only from the owners of Apple tablets - manufacturers of fashionable branded equipment made it possible to download their favorite tracks through only one source (iTunes), and the search for special versions of video files can cause some difficulties. The rest of the tablets running on the Android OS are much more democratic in this regard, and therefore you can safely enjoy watching your favorite movies and TV shows in high quality. And, of course, listening to your favorite music anywhere and anytime. However, answering questions about how much the tablet needs to be charged, and how long it holds the charge, it should be noted that such devices are significantly inferior to their predecessors - mp3 and mp4 players.
What are tablets for? In terms of shooting video and photos, they, like smartphones, can never compare with full-fledged cameras in quality. Not to mention how ridiculous a person will look who is trying to shoot a video or photograph something while holding a bulky tablet.
A truly useful device, and not just another fashion toy, a tablet can be for a student or a business person. Quick viewing of documents, Internet surfing, the ability to participate in video conferencing - all these functions make devices in this category really indispensable. Moreover, you can have access to them almost constantly, because even in specialist forums, when asked whether to turn off the tablet, in most cases you will get a negative answer. A tablet is primarily a 24/7 connection to the Internet.
Thus, the answer to questions about why tablets are needed and whether you need such a gadget directly depends on what exactly you expect from the device. Remember that most of the entertainment options may well replace other, cheaper and more compact devices.
