Modern smart devices offer awesome quasi-magical advantages over my very first computer which was a mobile pocket handheld computers I brought when I was 16, sporting Basic and 1.2kb RAM.
However, the distraction and mental load that comes with these devices and services these days is larger than any single human can reasonably consume in their life. The idea of ditching the smart devices and going back to paper notebooks and dumbphones the size of which I can _actually_ handle has been quite enticing to me too for the last decade or so. And I might actually do it some day.
Then again there's Google Maps, Communications, Notes, an ultra high end Digital camera, automatic sync and Backup, times and alert, notes, checkliste, calendar, groupware and a full blown VM with programming environment (I do Web) right there in my pocket. Star Trek is bronze Age compared.
Maybe it's just best to use these devices but work on the discipline in using them. A thing I'm equipped for better than anyone as an 80ies computer kid. The best way is probably some combination of both.
