Display
In the Samsung corner, we have the Galaxy Note II's 5.5-inch, 1280-x-720 screen, which calculates to 265 ppi. The display is a Super AMOLED HD panel, which stands for active matrix organic LED and means it doesn't use the Pentile sub-pixel arrangement. Like its predecessor, the Note II is fully compatible with Samsung's S Pen stylus, advantageous for content creation.
The iPad mini's 7.9-inch screen offers a one-handed iPad experience, but at 1024 x 768, the resolution is substantially lower than the Note II's, which puts the iPad mini at about 163 ppi, a substantial 102 fewer pixels per inch than the Note II. The screen is an IPS LCD, meaning it should have stellar viewing angles and work well in direct sunlight.
From a purely technical standpoint, the advantage goes to the Note II. However, depending on your content consumption preference, keep in mind that the Note II's 16:9 aspect ratio makes it ideal for watching video, whereas the iPad's 4:3 radio is better suited to reading.
