I've been using Windows 8 for months, beginning with the Consumer Preview that was announced at Mobile World Congress in February. Back then it was buggy and unstable, with as many problems as it had exciting new features. Now it's a stable, fast, powerful operating system — but that's not why I'll be switching this fall.
I'll be switching because Windows 8 is the first desktop operating system that understands what a computer is supposed to do in 2012, and it’s at once more productive and more fun than any OS I’ve used before.
