Depending on which new processor you have there have been some issues and patches sent out.

The good
A nice-looking and functional redesign that takes us past the Windows 8/10 design aesthetic.
Window management improvements are great across the board.
Performs about as well (and in some specific circumstances, better than) Windows 10 on the same hardware.
Raises awareness of security features like Secure Boot and TPM, which most people should be taking advantage of if they can.
Tons of beneficial tweaks to apps, touchscreen and pen support, and other fit-and-finish improvements.
Free upgrade from Windows 10.
The bad
Windows 11 is more consistent and unified than Windows 8 or Windows 10, but you'll still find traces of older Windows versions all over the place.
Taskbar regressions will annoy those who relied on the flexibility and customization options of older versions.
Widgets still feel mostly pointless in their latest iteration.
Lots of built-in apps haven't been updated yet.
General brand-new-major-OS-update bugginess.
The ugly
The biggest jump in Windows' system requirements in 15 years leaves plenty of perfectly functional and not-particularly-old PCs with no fully supported upgrade path.
