All of medtech has hard "expiry date". At the very least, accounts for mechanical/etc wear. Device may not be deployed after the expiry date.
If it were only to prop up the sales, the manuf could have simply shortened the "expiration" of their devices. They could have even installed some cheaper non-critical elements to justify the shorter life cycle.
I'd guess they done that already, but now want to extract even more from system.
Never had been a fan of the tabs feature (present elsewhere for decades now). It's bit like the browser tabs: it adds one more level of nesting, making switch between two windows a non-singular action, thus harder. It's fine as long as I'm sitting in this one application - but as soon as I need to involve 1-2 other applications into the workflow, then it simply messes up everything for me/requires too much of concentration. (It might have been a different matter if I could tab-ifying everything arbitrarily a-la older KDEs.)
P.S.
P.P.S. This is a very easily discernible pattern in the Win11 UX: almost everything now is 1-2 more clicks away, compared to other OSs. It's just plainly bad UI/UX.
Search for settings and options IMO is fine. "Settings" are by definition not user-friendly, since every time you need to tweak them is a case of something not working like you need it to.
The main problem is that you can never find settings that are not there anymore. Or settings for "new features" that are not really configurable (and you notice that as if entirely delivered via web).
Settings aside, on a more basic level, Win11 became the first Windows where MSPaint and Notepad, after many upgrades, stopped being useful general-purpose applications.
Start menu, that was OK-ish in Win10, was made useless. To me personally: entirely dysfunctional compared to search. (And Search now is even more eager to send you to the web search results.)
The Win11's Taskbar remains by far the most counter-productive "upgrade" ever. Yes, you can still disable "grouping" and show titles, but. You can't move Taskbar to left/right/top. You can't disable overflow. You can't have two rows. If you need 10+ windows open, then you are out of luck. MS Office/etc alone take 5+ windows. Need to switch constantly between 3-5 reference manuals and 2-3 IDEs? Tough luck. (Even wider displays are of limited help.)
P.S. At least one could still change Alt-Tab to work in the old-style task switcher, without "previews"/with icons-only. Hurray! Something in Win11 is working! It's not complete failure!
Win11 sucks.
It's simple as that. So far I found many UX regressions - but not a single improvement.
Best argument for upgrade was always that it was an upgrade. Now this gone too.
The universe is an island, surrounded by whatever it is that surrounds universes.
