I'd just like to interject for a moment. What you're referring to as LiveArea™,
is in fact, LiveArea™ UI, or as I've recently taken to calling it, LiveArea™ plus UI.
LiveArea™ is not a User Interface unto itself, but rather another properitary component
of the fully functioning LiveArea™ UI made useful by the Home Screen, Index screen
and vital LiveArea™ UI components comprising a full User Interface
All PSVita users run the LiveArea™ UI system every day,
without realizing it. Through a peculiar turn of events, LiveArea™ UI
which is widely used today is often called "LiveArea™", and many of its users are
not aware that it is basically the LiveArea™ UI system, developed by Sony Computer Entertainment
There really is a LiveArea™, and these people are using it, but it is just a
part of the system they use. LiveArea™ is the app start screen the one with
the buttons at the top, that looks like a peice of paper, that allow the vita
to start the other programs that you run. The LiveArea™ is an essential part of the PSVita,
but useless by itself; it can only function in the context of the complete LiveArea™ UI.
LiveArea™ is normally used in combination with the UI system: the whole system
is basically UI with LiveArea™ added, or LiveArea™ UI. All the so-called "Shell"
plugins are really plugins for LiveArea™ UI.
