Re: Dear Matias,
Roland, with that kind of thinking we would still be living in caves trying to rub two sticks together. Ideas must be tried and subjected to acceptance or rejection, it's called innovation.
Engineers don't always come up with the best ideas as they often design something from an engineer's point of view which is not immediately obvious to the user with lab equipment interfaces being a prime example. Touch interface innovation was a godsend in those situations as they are intuitive and alleviated the need for knowing obscure key press combinations to get to sub menus, additionally it allowed a much easier check of overall system parameters. It can still essentially be the same product but with a new human/machine interface.
