How to Detect iPad Mini Using Javascript (new method)

According to the SO item in the other thread:<p>"This is a detector of how many tabs are open. On my iPad 3 it reports different values when I have more than one tap open, matching the reports on the screen captures. The iPad mini screen capture has two tabs open, while the iPad 2 capture has only one. My iPad 3 reports matching values when I have one or two tabs open. – Mr. Berna 12 mins ago"

I don't think it works.<p>This is a screenshot from my iPad 2: <a href="http://i.imgur.com/eEzki.jpg" rel="nofollow">http://i.imgur.com/eEzki.jpg</a>

Question / concern here is why is it reporting this differently when in theory they should be the same?<p>It feels like something that might be "fixed" in a future release.<p>Unless anyone knows of a specific reason why this should be the case?

Update: It looks like these values are reporting viewport width and height at the time of tab creation and are not updated on rotation.
