I have been asking myself this question repeatedly for the last few months. Windows 11 offers absolutely nothing of substance over Windows 10 and more often than not manages to be less pleasant to use. The Office 365 eco system is a complete disaster of half implemented ideas, most of which can be described as would be pretty useful if it actually worked as advertised(power automate), wasn't abandoned in a half complete state(loosp), or if they implemented simple feature requests that the userbase is asking for(sharepoint). To top it all off they seem to be working tirelessly to ruin the products that actually work and are in demand, every couple of months they threaten to force users to switch to the 'modern' Outlook despite the fact that it still lacks a lot of features that are the very reason businesses still use Outlook in the first place.

Windows 11 has round corners.

Security knobs that Windows 10 lacks, better support for containers, WSL features, and DirectX 12 capabilities.

Granted, not everyone cares about them.

I find I no longer integrate new apps/technology flows into my life because they either won't be supported or will be enshitified/weaponized against me. The future kind of sucks. My smart home is barely hanging on to turning my lights on at dusk (something photo-sensors for lights just did without issue from the 90s on). Android just broke my phone, I can no longer just say 'hey android, play the news' and have it play headlines from real new organization that I specify. Instead it grabs news from I don't know where and gives me Google Gemini approved summaries (that Google states may or may not be accurate).
