I'm a COO and a senior project manager. Just regular office work. Office 365, Outlook, Word, Excel. CRM system, internal systems. All work is kept in Onedrive. I use Acrobat Pro a lot. Citrix Workspace. Sharepoint. Nothing really taxing like media content creation. The O365/Azure/Onedrive integration is great on my PC, it's just slow.
As an example, one small thing that I and I guess many working in Outlook do many many times each day is switch between mail and calendar in Outlook. On my PC it takes 2 - 5 seconds each time, sometimes even longer. On the M1 it's instant, on any Mac it's usually faster. It's a small thing - but over a day, a week, a decade spent in Outlook, it tallies up, both in time lost and irritation gained.
I know what you're aiming at - and I agree, it is solvable, it's not the end of the world, PCs are not useless, and that's NOT what I'm saying at all.
I was just trying to express how big a difference M1 is, especially for what it is considering price and ease of deployment. It IS a leap forward, that for once is accessible for basically anybody and I'll probably not die alone on that hill for sure.
