While historically I have not been a voracious reader, I came to realize that I could be better using my time in hotels instead of watching guilty pleasure TV. When I decided to start reading more, I realized that for longer periods of reading, my iPad Mini using my Amazon Kindle App was just not cutting it. It was heavier than I wanted and I was concerned about the high level of "blue light" might impact my sleep. Since I am often changing domestic time zones frequently, I didn't want to put my sleep at further risk.
With that in mind, I decided to purchase an Amazon Kindle Paperwhite. I really love it. It is light. 7.2 ounces (I did not get the 3G version which is slightly heavier since I am able to access Wi-Fi in most places even if I have to use my phone as a tether).
The battery life has been impressive for me. But, the main reason I choose the Paperwhite was because of the screen. Amazon touts it with the following info:
Won't tire your eyes in the dark: Kindle Paperwhite guides light toward the surface of the display with its built-in front light—unlike back-lit tablets that shine in your eyes—so you can read comfortably for hours without eyestrain. Adjust your screen's brightness for great reading in any light.
I really agree. It is easy to read on and the screen is adjustable but not overly bright.
I got my Paperwhite on sale so I only paid $90 instead of the current price of $120.
Verdict: I recommend it if you are wanting to read on the road. While I appreciate a desire to read a printed book, I can't carry the variety of books that I am able to with the e-reader.
