Well, I think this is a first: The New York Times has just issued an update to its iPad edition that say it is "Optimized for the iPad Mini" – notice the error on "Mini", which shouldn't be capitalized – we'll see that a lot I think.
Both NYTimes for iPad and NYTimes, the paper's mobile app, received updates this morning. The iPhone/iPod touch app was updated to improve the app's stability and to fix bugs.
So what does "iPad mini optimized" really mean? I can't tell you but I will be trying to find out. It will be interesting to see if there is a difference between the standard iPad tablet edition and a mini tablet edition.
