So, I wasn't sure about this based on the reviews.  When I got it in the mail I was skeptical if it would be a dud or not.  So far (4 months later), I'm pleasantly surprised.  The screen, keyboard, battery, and other components show little, if any, signs of wear, it powers up quickly and was a great upgrade from my tire old laptop.  I am familiar with the style of laptop because it is what my company provides, so I knew I wanted the 840 series for weight, battery, and size.
