how can the user benefit from a iPad Retina display?

If your a user of the retina iPad then when does the retina become useful?
For example do you notice it when reading text, does the text look better?
Do the photos you take with the iPad camera look sharper and clearer on the
retina iPad? Are there any apps that support this retina display ?

Often a feature gets advertised but its only of use if the user can benefit
from it.

 

any time you look at it.

most of them.

 

Whenever you look at the screen.

Yes, much better.

All photos, not just the ones taken with the iPad camera.

A heck of a lot of them.

 

Depends on how you define "of use." It's "of use" if it sells more product.

 

I suspect (but I've been too lazy to measure it) that "supporting the
retina display" means packing larger graphics files into the app,
sucking up more of your storage space.

And in most apps, the difference accomplishes nothing useful.

 

... unless you find the text clearer and easier to read, which I
certainly do. It may not be a deal-breaker, but for me the higher pixel
density is a well worthwhile improvement.

 

From the feedback I've been getting its seems like viewing a High
definition picture on TV compared to a standard definition picture when
comparing a iPad with Retina display.

Rather than rely on 3rd-hand information, most folk can just pop into a
suitable shop and see for themselves. Like HD, it rather depends on
your normal viewing distance, but closer up the difference is (to me)
immediately obvious.

 

Yes, the crystal clarity of the iPad 4's Retina display is nothing short
of stunning.

 

There's no denying that if you HAVE a "retina display" it is a bit more
pleasant to look at. But does it improve your aim in "angry birds"?
Does it reduce errors in your accounting? etc. One thing's certain:
it doesn't help you pack more music into the device.

So, whether the pleasantness is worth the (possible) loss of space is
up to each person to decide. Not that it makes much difference--the
programmers aren't asking whether you want it or not.

And if you don't have a retina display, tough beans. You get all the
disadvantages and none of the advantages.

 

What is this loss of space in your reply?

 

It's easier to exactly duplicate a shot, yes.

If you don't mistake a 0 for an 8 because the display is clearer, yes?

It also helps in reading, both on the web (especially shitty sites that
do grey on grey text) and in books/pdfs.

 

I doubt that, but I'll never know for sure because asa far as I am
concerned _nothing_ in "Angry Birds" has any practical value.

If that was a problem before the retina display, you need the
accessibility features or you foolishly selected a crappy app.
Plus, when accounting if you don't take steps to be usre of
a blurry digit, then you really don't care anyway, do you?

I don't waste time with those kind of websites. I did notice the
difference in iBook, but I had no trouble reading them before.
Again, I didn't ask whether it looks better, I asked whether
the visual difference is worth the cost.

 

"Enhanced for retina display" basically means that every image takes up
four times the storage, unless compression is increased (which reduces
the quality).

 

With the non-retina iPad I found my eyes would et tired and I'd start to
get a headache after a few hours of reading. No such problems with the
retina one.

What cost?

 

I would need to have a side by side comparison of both iPad models and most
stores are likely to only stock the newest model of the iPad.

 

Just recently while reading e-mail with the email program that came with
the iPad 2 I mistook a 6 for a 4. The order number was in small print. I
couldn't understand why they could not find my order when I phoned the
company.

 

So take a look on the Web first to find a store which has both....or I
have an iPad-1 I could sell you!

 

Not necessarily true. Both the 4th generation iPad and the iPad 2 are
available for sale. So both should be stocked.

 

When an app adds support for the retina display, any graphical objects
within the app need to be duplicated, including both a normal resolution
and an "@2x" retina resolution version of the graphical object.

The same build of the app is used on both non-retina and retina devices,
but only the appropriate graphical objects will be displayed. This means
that every app which supports retina display (which is most of them by
now, and is required for all new and updated apps) is wasting storage
space on every device, because half of the graphical objects in the app
will not be used on that particular device. The effect is worst for
non-retina models, because the graphical objects for retina displays are
four times larger than those for non-retina displays (due to having four
times as many pixels in the same area).

If the app is written to run natively on the iPhone and iPad, the
wastage is even worse, because it may need to include four instances of
each graphical object: for non-retina iPhones, retina iPhones,
non-retina iPads and retina iPads. (Apps with separate versions for the
iPhone and iPad avoid this problem.)

In some cases, further graphical objects may be needed to support the
different screen size of the iPhone 5.

In a few years this should be less of a problem because a future iOS
version will drop support for all older models which don't have a retina
display, therefore apps which require that future iOS version will no
longer need to include non-retina graphics.

That can't happen as soon as iOS 7, because iOS 7 will support the iPad
2 and iPad mini, which don't have a retina display. If an iPhone-only or
iPad-only app is run on an iPad 2 or iPad mini, the non-retina graphics
inside the app will be used.

In theory, a universal (native on iPhone and iPad) app which required
iOS 7 could drop the iPhone non-retina graphics, because iOS 7 doesn't
run on any iPhone or iPod Touch models with a non-retina display, and
the app will never display those graphical objects when running on an
iPad. It would still need graphical objects for retina iPhone,
non-retina iPad and retina iPad.
