Even if you jailbreak your iPhone, even if you install some Super-Extra-Power-Magnum-MultiTask-Fovever 2.0 Limited Edition in your iPhone, even if you manage to obtain some sort of active dashboard in your iPhone, how many apps could you keep opened at the same time with 256MB of RAM and no virtual memory? And how long will your battery live?

If people can get by without true multitasking, more power to them.To even discuss the point is kinda silly in this day and age.
When you're used to true multitasking (not just state-saving), anything less feels like a toy.

Before another "task" ("thread", "process", whatever it's called) can be run, the OS has to save the state of the current task (mostly CPU registers) to RAM so it can restore the state of the other task; therefore, multitasking is a form of state-saving (it's just done automatically by the OS many many times a second). You are right, though, in pointing out that some OSes essentially freeze the "backgrounded" tasks and won't give them slices of CPU time until the user "foregrounds" them, thereby effectively making those OSes single-tasking systems.Be careful with the term "real-time" though; it has very specific meanings in OS land, and the truth is that hardly anything runs in real-time and doesn't really need to. Hardware is so high powered these days, and typical user requirements (even developers and power users) don't necessarily require it.

Ok, ok. I meant multitasking as in context switching, VM, semaphores, etc.

Yeah.. and there's a laundry list of "if"'s that follow that statement including "if it was written by apple".
To me that's not truly multi-tasking... you should be able to run *any* two or more applications to qualify for me.
If I've helped you or you use any of my packages feel free to help me out.
