I thought this was interesting.  Maybe somebody who knows embedded systems could speculatively comment:   Is this because the threading or memory management that would be required for the applications to run simultaneously is too hard to do or would "break" the phone in other respects - such as diminishing responsiveness for phone calls or wrecking responsive user interfaces like precious coverflow?
