I don't know about the rest of you but I think Expose on the iPhone would be awesome. I mean wouldn't it be nice to have multiple programs running and having the ability to switch between them?
I realize that but I'm sure it wouldn't be hard to create a preemptive multitasking environment for the iPhone. Expose would simply give you the ability to switch between the apps assuming the ability to run multiple programs was there.
That's the whole point of wishing something would work a certain way. The OP would like it IF the iPhone allowed for an Expose-like program. I don't understand your quick dismissal to his/her wish.
