I love my Kindle. It allows me to read and buy a new book, and that’s it. Everything on it is oriented towards reading e-books. When you’re reading a book on it, there’s nothing else on the screen and no interruptions. I hate my smartphone. It allows me to do almost anything without a clear sign of what’s more important. I can receive a notification about a doctor’s appointment for my kids or the last offer from a random brand I bought from once; both can interrupt me in the same way.
