Backwards compatibility is important for Microsoft and us users. It's Windows 11 is a bit different in how many existing PC's it can run on, but it still runs apps that ran on Windows 10 (and before)I kind of hope Microsoft doesn't do what Apple does. Sure, the various Apple OSes are great and all, but it's hard to support an entire company/school district if various versions of the OS have different features. The frequent "You need a newer version of the OS to run this app" just makes it hard. I'm lucky to work in a school district since we get the summers off. With that, we can upgrade our fleet of devices fairly easily.
Apple, on the other hand, I don't now what they're thinking, and to tell the truth, I'm getting really annoyed with them right now. I may have already bought my last Apple product.
