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
Space saving design and light
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
I would gladly pay not to have McAfee (McRappy) bundled

Nothing wrong with the PC to be fair, however you couldn't upgrade the video card to the latest 1080 models.

For the people who said the graphics were bad when you were gaming, it could of been your monitor, not the PC. However, that's for you to decide upon.
