It's funny that, in an article describing issues with a high-DPI display, the author never explicitly says the size of the screen (e.g. in inches), or the DPI.

It's funny that, in an article describing issues with a high-DPI display, the author never explicitly says the size of the screen (e.g. in inches), or the DPI. He just tells us it's 3200x1800. In case you were wondering, the display on the Lenovo Yoga 2 Pro is a 13.3", 16:9, 276 DPI display. Personally, I find this description more immediately useful than saying that it's a 13.3", 3200x1800 display.
