Buying an EReader, Worth?

I am too fond of reading books in an electronic format. War and Peace by Leo Tolstoy, Hermen Hesse’s Siddhartha, My Inventions by Nikola Tesla, and A Brief History of Time by Stephen Hawking are some of the books I have managed to read on my smartphone using an ereader application this month. I have been in the habit of reading books on a smartphone since my teenage days and I find it quite portable and accessible at the same time. Major reason being I am carrying my phone almost everywhere and when I get time, I can sneak in a chapter or two anytime.

In recent days I have been thinking of buying an E-Reader, a proper one. The reason being is that, since I have started working, I have developed this habit of checking emails, getting notifications and checking them at the moment and these things usually leads to a distraction and many a times I lose my focus over the text. It is happening in a vigorous frequency in past six months such that I am unable to cope with my reading time. I have tried putting my phone on airplane mode, but since it is the only mean of communication I have, I have realised that I cannot do that for more than an hour a day. Anyone’s calling at any time and there is something to lose sometimes.

Thus, I have concluded to get my self a good EReader, one which offers good not-eye-straining-display, full of features like in-built dictionary. One thing I don’t like about reading a book on my current smartphone application is that there is no support for in-built dictionary and also reading PDF files is a big-headache. The options of taking notes, and highlighting text are must for me as I am used to highlighting words, lines, paragraphs, sometimes the whole page, whatever I find useful at the time.

Last night I was looking out for one, one that won’t leave big hole in my pocket and also satisfy my needs aforesaid. I got to know, these days, EReaders have become quite advanced. Not only they have built-in dictionary, there are many more offerings. I have set my eyes on Amazon Kindle Paperwhite 3 (or 2015 edition) but I want to hear from you guys first.

What EReader(s) do you use?

And, having a dedicated device just for reading, is it worth?
