Help me choose this e-book

Question

Electronic books

After another book read from a smart phone, I noticed that my eyes get tired from reading from a smartphone => as I understand it, the best solution is to buy an e-book? If yes, then help me choose a device according to the following parameters:

What would be connected to the PC as a USB flash drive and I just dropped the files there, without any stupid software. I have linux mint.

Supported formats:
PDF - unconditionally necessary, including scanned PDF
DJVU - I would be very glad to see, because there is a lot of literature in djvu, which I will read and convert every time to pdf with a size increase of 10 times - that's still a pleasure, probably. But if a really better book is without djvu support, I will buy it and I will convert it.
DOC / DOCX / TXT - will not be superfluous, although it does not play a special role.
I do not use other formats.

I will read from the reader, including scanned handwritten notes, so you need a good image quality, with a lot of shades of gray.

The faster the page refresh rate, the better.

Good, smooth and fast work with large files (pdf about 50mb).

Lighting is good, but not required. I understand that there is very little of it.

Sensory or not - not yet decided.

So that it does not break when lying in a bag.

Wi-Fi - I don’t understand why it’s needed there, just like all sorts of bluetooth, etc. The player is also not needed. In general, all these functions, if they exist, do not interfere with me, but there is no need to chase after him. A useful feature will also be the ability to split the file vertically, where there are 2 pages on 1 page, as in the ebook reader on android.

Bottom line: you need a high-quality and reliable device that has the listed functions, which will serve me for more than one year and will be sold because it will become obsolete and be replaced by something better.

It is better if the book is easy to find in local stores, but with a very noticeable benefit in terms of price, I can consider buying it on the Internet a la ebay.

Answer 1

I had several e-books and now an iPad. I will say this - it’s more convenient than an iPad for these purposes. The eyes do not get tired at all, the screen is excellent (even if not Retina). Instant flipping, color graphics. + as a bonus, the ability to CONVENIENTLY surf the Internet.
The batteries, of course, do not last as long as an e-book - but I never had a problem in putting it on charge every 3-4 days.
Now there is an iPad mini, which is just as convenient to read as on a large one, at a smaller size and price.

Answer 2

There is one problem with reading PDF: the books are designed to look like paper. In medicine, for example, it is common to make up a book in two columns in small print (a tradition of all American publishers). Such a PDF can only be read comfortably on a side-turned PocketBook 900 series with the largest possible screen, price and unnecessary WiFi whistles.
On books with small e-ink screens, reading such PDFs is more like peeping through a keyhole - very inconvenient.
With DJVU the same story is, first of all, scans of books and the text on them is not reformatted, unlike FB2. PocketBook read them.
The big screen is a moving problem. This is mostly a home book, it is easy to break it on the road - the cover does not save.

Answer 3

In my experience, PDFs are not really comfortable to read on anything. The best result of the ones I tested gives PocketBook Pro 902

Answer 4

I think for your purposes the reader is really not suitable. Well, you won’t be able to read pdf from them - because this is a format intended for printing, not for reading. And DJVU is generally not suitable for one or the other - all its advantages are that the books are smaller in size - only who needs it today. Completely useless format.
Even if the reader says that it supports scanned pdf - this does not mean at all that you can actually read it - without font size control it will be very difficult for you - believe me.
You might be able to read a 9-inch or larger e-reader by flipping it to landscape - but it's still not convenient.
However, with the tablet there will be the same story as with the book reader. Only maybe the scaling software will be a little more developed - but it still won't save you.
I would recommend that you buy a printer instead of a reader. PDF invented for printing? - so print your PDF and DJVU books - and read them like that. And there won't be any problems. This is a real topic - no jokes.
There are special book formats for reading on screens.

Answer 5

Are Kindles really better or not?
If we compare the most popular readers today: Kindle and PocketBook, then in my opinion the situation is as follows.
I will describe the benefits of each.
PocketBook
1) It's easier to buy in Russia. Kindles are not officially delivered to us (only at foreign online auctions).
2) Native localization into Russian. In the Kindle only from the Internet.
3) Some exotic formats are supported out of the box, which the Kindle (again, out of the box) does not understand - DJVU is among them. But as I said - as with pdf - this is a dead number, it's still read like that.
4) Slightly more developed software for working with different types of documents. That is, the Kindle followed the path of one format with auto-convert services when sent to the Kindle. A pocketbook has more software inside itself.
5) Dictionaries for Russian and English out of the box. The Kindle only downloads from the Internet.
6) A lot of additional software, like watches, etc.
The Kindle has almost nothing, except the ability to read books, take notes, dictionaries and audio, that is, only the most important thing.
Amazon Kindle
1) It's much cheaper.
2) It has a better screen, it scrolls faster, it has a better size (thickness, weight, comfort in the hand) - in my opinion, all the attributes related to simple book reading scenarios are better.
3) Its warranty works worldwide and includes a refund in case of a broken screen - this is the most common failure in book readers - the screen is very fragile. Pocketbook does not give such a guarantee.
4) To drop books on the Kindle, not a usb cable is used, but wifi. You need to install a special program on your computer, after which the book can be sent through the context menu. Or you can send it to the Kindle by mail.
After that, the book is automatically converted to the desired format and sent to the device and to the amazon cloud storage that will be provided to you.
This is much more convenient than the archaic ways to throw off books.
Work through yusbi is possible - but not supported by Amazon at all.
To do this, you will have to install a special program from the Internet - which can send books to the reader - but as I said - this is not out of the box - and in general for fans of antiquity.

Answer 6

PocketBook 611 or 903.
