So, uhm, I’m not a fan of Windows 8, but why exactly is this in any way a big deal?

It's not finished. It will break. You have a backup device (or two) ready when you present it in front of a crowd.

Apple does it (I remember keynotes where they had to switch to their backup Mac), Microsoft does it, everyone does it.

I'm an Apple fan, and I agree, stuff breaks. This is a non-news story.
