Very good price
Very easy to setup. Attach stand with thumbscrew , connect power cable, keyboard mouse. .. done
Big 1080p touchscreen, it looks like a TV display
Good way of introducing Windows 8 to users

Could become sluggish when pushed to its limits. But for the intended use (kids PC) is more than enough
Lack of USB 3.0
I would have liked an HDMI in
1 MP webcam. An extra megapixel would have help a lot
