Re: How?
Nope - no confusion at all, but a recognition that desktop class performance no longer requires a sizable power bill.
The M1 is a very capable processor, and will burn through most tasks that your desktop workhorse accomplishes very capably.
What it will never be is a racehorse - it's not going to replace a full tower top end, wannabe server, workstation (as opposed to a desktop), but noone has pretended it will - that's for the next couple of generations of chips if the rumours are anything close to accurate.
95% of the time it's a computer, the remaining 5% it's a computer I can take with me and carry on working. As opposed to your approach where 95% of the time it's a computer, the other 5% of the time it's nothing, because you now can't work when you visit the office...
That's no reason not to make it a comfortable computer for the 95%, monitors, keyboard, mouse/trackpad/trackball, external storage, high speed networking...
