Which PC/gadget has the highest pixel resolution?

Here I have collected and calculated PPI (Pixels per Inch) for some laptops and tablets.

15.61.780.5113.607.65128072094.14HP Pavilion 2000T

So far, nothing can beat Amazon Kindle HDX, not HP not even Apple iPad with Retina display.  Because the price of a laptop is significantly higher with higher PPI, the affordable price of Kindle plus its highest PPI makes it the best gadget for eyes and pocket!
