I think you're missing something here.  Some (many?) cognitive tasks
require support from more than 1 application program.  For example, I
regularly debug programs with 3 windows open:  an editor, a debugger,
and the running program.  Even if you had 1 application supporting these
3 things, you'd still need 3 sub-windows to display them all.
Many advanced user interfaces are similar.  There's often one spatial
display window (e.g., a map or image or a spreadsheet), one abstract display
window (e.g., some statistical analysis graphs, etc.), and one control panel
window.  That's 3 windows even for a narrow (but sophisticated) application.
I'd hate to see someone fly a plane (or even drive a car) if he could look out
the window or look at his guages, but not both at the same time.
