>I've also discovered that it's having a negative effect on my ability to focus. I used to read a book a week. I haven't read a book since I got a smartphone. I can't. I got a smartphone recently. I put a lot of ebooks that I read in my commute with inverted colors (white text on black background). I charge the phone every 3 or 4 days: I don't listen to music on it, I don't take pictures, I rarely if ever go online using it. The home screen is black (took a picture with finger on the lens because I was too lazy to download a "black" image).
