I agree, but then you wouldn't mount automatic transmission on a MC even though many people feel it is a necessity on a car.

It is user experience of the end product that counts, not some features of the OS.

IMO the user experience is much better with multitasking, but having a fluent and dead easy user experience is obviously more important for most people. Just knowing that you can push the "home" button and the phone is back to the same state as if just rebooted, is a revelation for most people. That way they know they can't "mess up". That is about as much complication they can handle.

For some people multitasking is second nature. I don't think you will get more than 5% market share if your focus is on those people though. The optimum is to make multitasking invisible for everyday use, yet enable some control for those who want it. ICS seems to at least try to do it correct.
