&#62;Multitasking doesn't need to add complexity and stability issues, if ubuntu can do it then so can apple.<p>That it can be done doesn't mean it isn't complex.  It is.<p>And by "stability" I didn't mean the phone/tablet constantly crashing, I meant having inconsistent performance.  Once you get into multitasking, everyone and their brother is going to have some really "good" reason they need a service.  Some of these will always perform well, some wont.<p>&#62;Multitasking is useful because humans are multitasking.<p>Humans are incredibly awful at multitasking.<p>&#62;Single tasking computers are pretty much done for, multi tasking is the norm, not the exception.<p>Computers sure.  But this is an instant-on consumer device.  I think the use cases for such a device are different enough to warrant at least consideration for a different kind of OS for them.
