Well, are there any adventurous, early adopters out there that have upgraded their PC's to Windows 8?

I am using Windows 7 Pro and I qualify for a discounted upgrade to Windows 8 Pro - I only pay $14.99 for the upgrade.

I am burning with curiosity to see what it's like, but I am also a little nervous to take the plunge just yet.

Should I do it now, or should I wait?
