The idea that a personal computer is a good idea is just insane, for this reason:
You're going to be connected to a mainframe anyway.
Even if your personal computer did have enough storage and power you're still going to want connect to the mainframe to access reports and data.
So if you're going to have a connection to a mainframe anyway, why bother with all that local computing power?

I'm not saying it's a good idea in the current ecosystem but there are advantages to the watch having it's own network connectivity, and in fact I believe the current watch does connect directly to your wifi access point using credentials shared by the phone when possible.
The main issue with watch cellular access at the moment, is cost of paying for a phone contract for a watch, when at least at the moment, you will probably want a phone too.
I believe that misses the point entirely. Forgetting the fact that I never even saw a mainframe until the late 90s, back in the PC day you were still using the same keyboard + monitor for both.
I like the mainframe PC analogy but I think in this case we are running up against ergonomics. People's hands are not shrinking and our eyes aren't getting any better. More interface may get offloaded to audio/voice, but we are such visual creatures. Until we are beaming data directly into our eyes, I don't think we will abandon the palm-sized display-- maybe foldable one like paper, or a tattoo, or my shirt sleave, but something.
Except it was never the case in any country that ~70% of people had access to a mainframe at work, let alone home. If a much smaller percentage of people had smartphones and putting cellular on a watch was cheaper/more convenient enough to get the rest of the population on board, then your comparison would make some sense.
