Windows 8 Good? or Bad?

I havent had the chance to use Windows 8 yet, but I have seen demos and talked to other individuals abotu it. They all seem to like it. www.Techradar.com rates windows 8 at 4 1/2 stars. I personally think it will be great for tablets and laptops with touch screens, even desktops that have a touch screen feature. Microsoft is stepping in the right direction to try and keep up with IPads.
