Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I use an iOS phone and tablet, and I use iCloud on my PC. For example, it's convenient for scheduling appointments and reminders from the PC (but the interface is crippled--e.g., you can't set travel time, and you can't set up a custom recurrence like the 2nd and 4th Thursday of each month, in iCloud for PC. I have to go to an iOSdevice to specify this). But it won't even let you see/send sms/mms/iMessage messages on your PC.
Another big reason for considering the switch is the fact that when I interviewed (unsuccessfully) for a SWDEV position at Google, everyone seemed to use Macs. Also, the underlying Unix nature of modern versions of MacOS would be very convenient; I get tired of the quirks/incompatibilities of Cygwin on Windows.
So it's for a variety of reasons.
But thank you for the helpful suggestion.
