It depends on the distance you're holding the device/printed material. This article explains it all in pretty good depth. At four inches from the eye (closest most adults can focus), the max is actually 2,190 dpi. At one foot, it's 720dpi, but 300dpi at that distance is the max that the average person can really distinguish.

So 300dpi is definitely not the absolute max.
