The Kindle app for iPad has just received an update, and it adds a feature I’ve long wanted: When you read in landscape mode, it now shows up as two columns. So far, it’s one of the main reasons I preferred reading books in iBooks, because having two columns like that (or two paperback-like pages) is the width I like to deal with. Reading in portrait mode (for both), I find that the column width is just too wide to make for a comfortable read.
