In order to work I need to physically separate my device from me. After a an hour or two I retrieve it because it holds ancient knowledge of notifications of hours passed. Funnily enough, when I'm really engrossed in something, I'll forget my phone for stretches of 4 or 5 hours or more. Unfortunately, "engrossed" is not a word I'd use to describe myself at work.
If only there was a device that I could play Spotify from, and use Google Maps on, and text from, and occasionally browse the internet from, and use as an alarm, and todo-list from, and create reminders, and keep all the other useful and flexible functions, without being distracting.
On another note, I don't think I've gone to sleep nor woken up on time since I got my first smartphone in 2015. Could be a coincidence.
