I'm not sure that I agree. Jobs had realised that, if he could make it work, a system for controlling a smart phone using fingers on the screen would provide a far more versatile interface. With auto wipe and auto high beam, the user derives no advantage from the underlying technology unless it provides a better result. Given that these systems, for example as implemented on my BMW 540i, work flawlessly using existing technology, there can be no advantage in developing an alternative way of trying to achieve the exact same thing.The analogy I would use is Steve jobs could have used a scroll wheel like blackberry or a stylus like treo but he went for using our fingers which wasn’t tried and tested and introduced lots of errors. Now where are those styluses and scroll wheels!
