The perfect device for people who want to live a phone-free life is a smartwatch. But not the Apple Watch (yet; see below). Because it should be a truly standalone smartwatch, without any dependency (does not require any other device for anything, including setup, although I would accept it if it required a Mac; I do NOT want to own a standard smartphone, not even for free!) and has a telescopic rotating retractable camera, protected from dust and sweat when hidden in what seems the crown neck. Besides, the telescopic camera is a great safety and privacy bonus, since it is only visible and active when you extract it manually.
It is like a miniaturized smartwatch with all its capabilities. You carry it in your wrist and do not notice it. Your hands and mind are free. You do not drop-break it or lose it. Not even thieves look for it. You can sleep with it and use a vibrating alarm to not disturb others when needed.
Amazingly, it costs about 100 USD ($), although I would buy one for ~1,000 from Apple if they made it as well. Unfortunately, they do not do it yet. But at least I have the cheaper one.
One last word. It is really amazing. It has changed my life!
