BTW, I have no idea what you mean by "multitasks, but not in a
freewheeling way". What does it mean to have a freewheeling
multitasking operating system?
"not freewheeling" is just an informal way of describing this situation:
iOS apps aren't inherently multitasking, to run in the background they
must implement a method which handles the backgrounding event, and there
are certain limits, not the least of which is that only some services
(e.g. audio) can run continuously in the background; other background
processing is suspended after ten minutes, and background apps may be
terminated when memory is needed for a foreground app
I can have several apps doing processing simultaneously, they
represent individual processes that each get a guaranteed, prioritized
time slice on the processor . That's what multitasking means.
i did write "the iPad multitasks", but using your definition i'd say iOS
gives more of a "limited warranty" than a guarantee
