Don't go for full functionality when buying an ebook reader
Some friends buy e-book readers, hoping to have all functions, the more the better. In fact, this is a typical misunderstanding. The main function of an e-book reader is to read books, just like a mobile phone, mainly for making calls. Some mobile phones have many additional functions, and some friends may experience it. Phone calls, sending and receiving text messages, and other camera and radio functions are rarely used. Mobile phones can also use MP3 to read TXT novels, but how many people use their mobile phones to listen to MP3s and read novels. At most, they use them occasionally when they are bored.
Therefore, it is recommended that friends buy an e-book reader to figure out the main purpose, and those dispensable uses are not necessarily. If you want to listen to music, you might as well buy an MP3.
Buy e-book readers try to buy mainstream products
In fact, the replacement of e-book readers is very slow compared to other electronic products. Generally, a product will be sold for one or two years. It is rarely like a mobile phone, and the price is reduced several times a month. New products come out every month. We recommend that all friends buy e-book readers as far as possible, and try to buy mainstream products. Generally speaking, mainstream products are relatively new products that have passed the use test of the majority of users and are recognized by everyone. . Usually products that have been discontinued for more than a year, we do not recommend buying them.
