I only do light webstuff and messages from a mobile, if I need to do real work, I either dock the company laptop (multiple displays) or I sit infront of my desktop PC (multiple displays).
If I tried doing my job from a smartphone I would get very frustrated (wrong tool for the job) and be looking for a new job very soon (productivity drop).
SoMe is not doing work in my book
But "real work" was never really the justification for a
personal computer. That’s an extension of running a terminal connected to the company mainframe back in the 1960s (that we are conceptually moving back towards, ironically enough.)
Rather, a personal computer (if you move outside the x86/MS definition) could arguably be for doing personal stuff. And then it’s clear that these days, mobile devices largely fill that function. My very elderly parents ditched their last computer once they discovered iPads, and my daughters regard laptops as overly heavy tablets, with a keyboard inexplicably and annoyingly permanently attached.
They do all their messaging, photography (and sharing), videos (and sharing), banking, booking, gaming, watching films, listening to music and sharing playlists, searching, shopping, et cetera, on mobile devices. They have no interest in either a Windows or MacOS computer, hell even our administration at work is dropping their O365 subscription and moving to OS agnostic solutions for all their tasks.
Personal computers as we knew them say twenty years ago, are largely legacy devices.
And for quite some years Crapple did (properly still do, I have no clue as they have zero products for me and I pay the no interest) sell exactly the same hardware as "PC's"...just RDF kicking in again and warping "reality" /shrugs
Well they did package them nicely. And they did run MacOS, which provided some benefits and drawbacks that suited some.
And of course these days they are moving to their own hardware again, but conceptually these are the same as their old x86 machines, only with hardware that is better suited to the task. Which is nice, but does nothing to move them out of that legacy+work niche.
