Would you rather be able to do everything with one thing? Say, listen to music, take pictures, play, work and whatever with one device? Or would you rather have a specific device for listening to music, a specific device for taking pictures, a specific device for work and another one to play and such?
I personally prefer to keep things separate these days. On a practical level it means that I don’t depend entirely on a single object and that, if gets lost, damaged or runs out of battery, would let me with nothing at all. On a subjective level, I feel that having specialized objects for each need gives more weight to the routines I create with them, contrary to when I kept everything in one place and it felt superfluous and banal.
So far I have an old phone that I use as an MP3 player, an old tablet as an EBook, my old Ps2 to play games and so on.
In the past, I would have said “One device to rule them all” but then we got the modern smartphone which does all the things, but none of them exceptionally well (and definitely not ergonomically or frustration-free).
I’ve upgraded to a dumb-ish flip phone which is good for phone, texts, and music (has enough buttons i can key-map to have physical controls when it’s closed). Everything else, I’ve started preferring dedicated devices (e-reader, camera, my actual wallet/cards, etc). In a box somewhere, I think I still have my 1 GB MP3 player that will run for like 2 weeks from a single AAA battery. Would love to find that.
My old smartphones are also single-purpose devices, repurposed into HomeAssistant remotes, Emby controllers, VoIP handsets, etc).
