One thing about the Kindle itself won’t change, though: It’s not going to become anything more than a reading device. Amazon’s heard from so many customers over the years that they love their Kindle precisely for all the things it doesn’t do. It’s a respite from Facebook and news alerts, push notifications and emails. “The more that we’re distracted, the more valuable solitude becomes,” says Dave Limp, Amazon’s head of hardware. “The last thing I want is being absorbed into an author’s story, and get an uplevel notification for Angry Birds.” Reading is about focus, about falling out of your life and into a story, and so the Kindle is about those things too. - Plateau Kindle Before Peak Kindle
I started using the Kindle Paperwhite since beginning of 2017, just with the intention to try it out. Before that I used an iPad Mini for reading eBooks, but the battery would just go empty fast and it was just too big after long time holding in my opinion. Since then I’m reading one eBook after another on the Kindle. I also agree with the quote above.
Furthermore the e-ink screen is more pleasent than the display of the iPad for reading. One disadvantage is that the screen still affected my sleep quality, so before bed I currently read printed books since a while ago.
