Summary: Great price and works well when plugged into the adapter. The shortcomings were that the screen would dim to the point of unusable when not plugged in. There was no way to adjust this. Also, this did not have auto orientation. It would be either set in portrait or landscape mode. It does not automatically change when you turn the computer. No bluetooth. I will say that I'm running a beta version of Windows 8 so it may work fine with Windows 7.
