Oh, my goodness. I'll give you three (3) that were driving me nuts throughout the pandemic...
(a) Compatibility. Here's an easy one: try using multiple screens/monitors with different resolutions in Windows 10 (e.g., 1080p screen, 720p TV or projector, etc.). --Let me know how that goes, that alone could convince anyone.
(b) Speed. For my workflow, I have a Dell laptop from my work, running i7, 16GB RAM, etc., it works but just barely--throttles constantly (high fans, hot chassis, etc.) under load, a tantrum with multiple screens, anti-virus constantly needs to be updated, defragmenting is still a thing, updates sometimes need multiple reboots, etc. --Seriously, who the F has time for any of this?
Now, that fancy Dell with Windows 10 quite a bit newer yet has nearly the same specs as my 15" MacBook Pro (mid-'17) that just turned four, and the differences are night-and-day on everything from booting it, waking it, typing on it, etc. -- From days-to-weeks-and-sometimes-months I leave the MacBook Pro running on the original boot, sleeping and waking as needed, and have no issues; however, the Dell will have nothing short of a full blown conniption of I plug in a banal 1080p external monitor or a 720p television set.
(c) Death-by-updates. My favorite thing to do with Windows is leave the machine off for several months (e.g., Summer break, vacation, etc.) then boot it for a project in the fall, and have it go through a gazillion software updates, not to mention the "Your computer will restart in 10 minutes" messages. The machine has only been off for a few weeks, sometimes over the summer, and it's like I had just bought it all over again--updates, updates, updates. Christ, one would I have nothing better to do than watch Windows go through another restart after it just completed one on the previous update.
Honorable Mention: I love being asked to "authenticate" my Enterprise edition of Windows every six months or so, and have to call my IT dept to get it re-re-re-authenticated because it's not seeing the main enterprise server (because I'm working remotely). I love having to setup a VPN so they can remote access/control to update the authentication key and I can work. --Again, who the F has time for any of this? Plus, I just love those endless pop-ups about "Windows Authentication...your license will expire in two days...you will lose access...etc.etc."
Whether it's a top-of-the-line MacBook Pro or even a cheap Chromebook, I have never had to deal with this nonsense. Frankly, who on earth has time to deal with any of it?
