I think the main reason Microsoft launched Windows 11 was to get people excited about PC's again. Year after year people are getting new 1,000 dollar phones but are very rarely buying new pc's.
I can see some of the people with older pc's having negative views as Windows 11 offers less or even nothing at all to older pc's.
I have a 2 in 1 device myself and can say Windows 11 absolutely does bring improvements. Windows 10 tablet mode was stupid, I much prefer the tablet function maintaining the windows design found in 11. So that is just one improvement.
Also a lot of newer tech trends just works better. HDR screens, integration on things such as gaming and several other things that are overlooked by people that just don't have the newer tech yet. In a lot of instances it will be the new pc's that take advantage of what windows 11has to offer
The start menu does have some controversy. But who cares about that anymore, just look at all the work that has been put into start 11. Easy fix at this point.
