I'm frankly amazed that the majority of new laptops still come with Microsoft Windows.

To be fair, over the years there have been sincere efforts to re-architect the OS with a security, privacy, reliability for peristent storage, graphics, multi-tasking, multi-user, networking etc. But those efforts never caught up with the speed at which bloat was added.

At the heart, its design still has remnants that have the naivety of a stand-alone, stateless microcomputer that boots straight off a floppy after BIOS POST.
