EssentialParado said:I believe that the design that Apple does finally implement will need to be as obvious and clear as possible to the user of what they're doing, without having to teach them a complicated UI.
There is already a simple and elegant multi-tasking interface, that's been available on JB'ed iPhones for some time. It's called ProSwitcher:

It doesn't require any odd interface modes or impose any artificial limitations on a number of concurrent apps. The interface is immediately familiar to anyone who has switched between tabs in mobile Safari.
I use this all the time on my 3GS, so I KNOW it works as you would expect. If Apple could natively implement something like ProSwitcher on iPhone/iTab, I (and I suspect many others) would be happy campers.
