Technological progress improves the comfort and quality of our lives, like water, it fills all our spheres. He also touched upon such a favorite human pastime as reading. Thanks to this, there is no need to go to the library and carry heavy volumes with you or wait in line for a book that is available in one copy; it is enough to become the owner of a convenient device called an e-book. Book models produced today have a large amount of memory, a powerful battery charge and support many formats, and also contain various add-ons. So what properties are it important to pay attention to first when buying a gadget?
Types of screens
New models of e-books use a special type of E-ink display. These screens use e-paper technology to simulate printed sheets. Reading text from this screen is very convenient and is closest to reading a printed paper book. Today, the most widespread is the new generation of E-ink Pearl displays. The main advantages of a book with electronic ink are energy saving and minimal impact on human vision. Disadvantages include the need for an additional light source when reading, slow turning of text, and the inability to watch videos. To solve some problems, some book models are equipped with backlighting.
The second equally common type of screen is liquid crystal displays. The advantage of such a screen is the ability to display a large number of colors, the ability to install games and watch videos, as well as a built-in light source. Unfortunately, the presence of additional functions leads to increased energy consumption. Also, this type of screen quickly tires the eyes and has a detrimental effect on vision.
Memory
Current e-books can accommodate ten thousand books, which is equivalent to having your own small library. As a rule, a budget device will have enough native memory for a thousand volumes of A Song of Ice and Fire. However, if this does not seem enough to someone, then there is almost always a slot for various types of memory cards, which will allow the owner of an inexpensive device to carry with them a volume of books the size of a personal collection of Stephen King books (and it is impressive). Also, some e-book companies create a network library for their customers, accessible to the owner via the Internet, where it is possible to purchase virtually any book.
Various formats
In addition to all existing formats, many users mistakenly think that pdf is the most convenient for readers. Be that as it may, text in this format is often reproduced with errors, since the book’s screen is smaller than the document’s standard resolution. Try to choose a book model that accepts the most common extensions: doc, txt, fb2.
Additional functions:
- Play audio files. These can be either musical works by your favorite authors or audio books. Different models offer different audio output options, from headphones to built-in speakers.
- Ability to open formats such as jpeg, bmp, etc. This will make it possible to store photographs and images by dumping them into the book’s memory.
- Ability to view videos. Available option for LCD displays.
How to choose the most convenient gadget for yourself?
First, decide which type of screen will be more comfortable to use. The next step is to analyze the functionality provided by various models and choose the one you need for personal use. If you are only interested in reading, then a budget option from any company will do. For a student of foreign languages, it would be better to have a book that not only reproduces the text, but also has the ability to read audio formats.
When purchasing, take a close look at the battery capacity; the longest battery life of your device will depend on it. It is very important to choose a protective case for your e-reader; it will help keep your device in pristine condition without severe damage or scratches, and don’t forget to buy a special cloth to care for the rather sensitive screen.
The presence of downloaded texts upon purchase will allow you to quickly and comfortably check the functionality of the device. The happy owner will also be very pleased with one of the most pleasant additions when purchasing an e-book - the ability to find on the Internet the work of almost any author at a very low price or even for free.
Before purchasing, you should definitely read reviews about the model you like, compare devices of the same category from different manufacturers, and read tips from various users of such books.
