Apple has snuck a couple of new features into their apps pages in iTunes, specifically an information popup with tabbed content remarkably similar to how Google presents Android Market details. We know that in the past Android has been accused of copying Apple, but like Notification Center this time it looks like Apple is the one caught with their fingers in the copy jar.
The iTunes pop-up windows are activated by a new information icon which will appear when hovering over an app icon. The purpose of this is to make things easier -- the information appears right in front of you now without having to click through and load a new page. Movies and TV shows are also getting in on the action, although they'll have a play button to preview a clip of the video instead.
