Actually they take isolation from an external source for granted  but within
processes with the exception of critical apps like banking they take
interoperability for granted and probably don't expect isolation between
communicating apps.  I remember one project I did where I provided a new app
and Office apps to 200 people running macs and other platforms but since
Excel and Word did not interoperate seamlessly (DDE/OLE / Drag and drop)
there was a lot of anger and dissatisfaction. When a later version allowed
some of this ,they were happy and if a virus spread from excel to word this
way they would accept and understand that. 

I suppose the big issue here is Keyloggers which with existing GUIs and 3D
system can read what you type. Changing existing systems GUIs and 3D systems
to not allow keyboard hooks is a challenge since with admin access you can
do anything and most harmless programs really on this you really need to
start with a new OS.
