With dual orientation, when you turn the iPad, it will go to the corresponding page in the layout.

BTW, I’ve come to absolutely hate dual orientation publications and unless you have some overriding reason to do it this way, I’d be looking at other methods.

There's one reason that rises above all... CUSTOMER DEMAND!

People are not buying gimicks, they want good qaulity content.

I can guarantee that a quality publication with one orientation will outsell a dual orientation publication with dreck content.

They’re not only less labor intensive but a whole lot smaller on the file size as well.

@nz_geographic,

By "customer demand" I'm referring to the publisher and not to the actual reader.

From some reason, all the publishers I'm working with tend to favor dual orientation.

@Bob,

Personally, I've seen magazines switch from dual to single orientation and found it to be a very wise decision.

On the design team manager side, I totally agree with you. Dual orientations is much more hassle. If it was to me, I'd suggest that they'll abandon the whole dual orientation idea, make the choice between portrait or landscape and stick with it for eternity, but if they're willing to pay for the extra work and time required to create the 2nd orientation (which they do), then they'll get it.

On the reader side, I sometimes find it easier to switch between orientations in different reading poses.

In a small experiment I run during one of my DPS classes, I asked 23 students to download a simple tutorial folio to thier tablet device and follow it to create the described overlay effect. They were not told that the folio had both orientations.

The result: 5 didn't even check for existing orientations and used the portrait. Out of the 18 that did, 11 used the portrait orientation, while 7 found the landscape suits them better.
