Generally speaking, I feel that kindle is very suitable for linear reading of leisure works (novels, essays, poems, cartoons, etc.). ). For the "theoretical monographs" and "teaching materials" that need continuous attention, the "slow refresh" reading experience of kindle will seriously affect reading ideas. In other words, the kindle is used to read "casual books". I strongly feel that people who are very satisfied with kindle are those who read idle books and those who read pure liberal arts theoretical works; Or reading is not large enough, and skimming skills are rarely used.

The original kindle system supports azw, pdf, mobi, prc and txt formats. Among them, mobi, azw and prc formats are the best. If you scan a PDF, the display will be unclear because it is not tailored to 6 inches, or it will be unclear because the scanning effect itself is not good. If the word is too small, the original system can consider local amplification, and the intelligent pruning function can be used under the system. Txt format support is not very good, there may be garbled or page turning problems. It would be better to save the txt format encoding as UTF-8 encoding (open a txt file in your computer and click File → Save as → Select UTF-8 encoding → Save), but it is recommended to convert it to mobi.
