Ok so 40Gb might not be a huge amount of space this day and age but for use as a boot hard disk it's perfect and my system has never been as quick as this before. Fantastic price, fantastic... Read more…

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
