Windows 11 in detail: Incremental upgrade spoilt by onerous system requirements and usability mis-steps
Here's the summary:

Windows 11 looks better than Windows 10 and is an incremental update which in the normal course of events users would welcome. The launch though is spoiled by system requirements which seem tone-deaf to today's component shortages and ecological challenges, and by changes to the core applications which have sufficient annoyances that some users will prefer to stick with Windows 10 for a while; it is supported until October 2025. Windows 11 will no doubt get better in most respects, though Microsoft's insistence on using its operating system as a vehicle for promoting its search and cloud services, where it gets in the way of usability, may be a persistent concern.
