Next-generation iPhones likely to focus on internal improvements.
Apple Exploring 3D Desktop and Application Interfaces
Disclosed herein are systems, aparatus and methods, including a multidimensional desktop graphical user interface.In one titled Multidimensional Desktop, Apple includes a number of diagrams depicting what such a desktop might look like and how it would work.
This figure (above) shows a multidimensional desktop environment alongside what Apple describes as a multidimensional application environment. Along the side are a number of three-dimensional "function" icons that may trigger certain commands on each surface. These icons can be manipulated in 3D with a physics model so the icons can appropriately "fall" if displaced.
This figure (above) shows that windows could be dragged or displaced across multiple surfaces. Each surface could have its own characteristics and cause icons or windows to display different information:
For example, on the bottom surface, icons and other system object representations can be displayed according to a large scale; on the side surface, icons and system object representations can be displayed according to small scale; on the back surface, icons and other system object representations can be displayed in a list format
It's not clear when and if Apple will decide to implement these design ideas into a future version of Mac OS X. Apple's next major version of Mac OS X (10.6) is due in the first quarter of 2009 and will primarily focus on "under the hood" changes to boost performance. Apple has not been the only one working on 3D desktops. One popular YouTube video demos a 3D desktop in action. Sun's Project Looking Glass also demonstrates a currently functional 3D desktop for linux and Solaris x86.
