The question is, what does the Retina display actually mean
for you?
To start, it's worth defining what Apple means by Retina. In
simple terms, it means that you can't distinguish between individual pixels at
normal viewing distances. As such, the pixel density – measured in pixels per
inch (PPI) - is the important factor in distinguishing a Retina display from a
regular one. As the viewing distance changes on the device and screen size, the
required pixel density for Retina changes.
So, the Apple
iPhone 4s, which has a 3.5in, 640x960 screen, has a pixel density of
326ppi. This high density is required, because you hold the phone so close to
your face when using it. With the new iPad,
which has a 10.1in, 2,048x1,536 screen, the pixel density is 264ppi, as it's
designed to be used from further away. The new MacBook Pro with Retina display
has a lower pixel density of 220ppi, as it's designed to be used from further
away again. As a comparison a standard 15.4in display with a resolution of
1,920x1,080 has a pixel density of just 147ppi.
What Retina means in practice is that text and photos look
much sharper, because you can't see individual pixels, you can't see any jaggy
lines, as you may do on lower pixel-density displays. For the best results
applications have to be designed to at this kind of resolution. This means
ensuring that high-resolution graphics and icons are available, as simply
blowing up existing graphics and text loses quality and detail.
