Does the latest Kindle for iOS app have a multi-column option for reading books? I had an iPad1 until about 6 months ago, but I cannot remember if it had that option. I'm thinking of getting an iPad3. However if the Kindle app does not have multi-columns in landscape mode then it will not be pleasant reading in landscape, which is my favorite way to read on a large tablet.

In my case the iPad1 was no good for prolonged reading with its lower resolution screen as it caused a lot of eye strain. The new Retina display iPad3 shouldn't be a problem though. I have an iPod touch 4th Gen with Retina display and it is good for reading, but of course a small 3.5 inch screen is not so good for reading.
