As you have guessed right, I have absolutely NO idea about Software development. I was lead to believe that it is easy to write software for the iPhone by numerous articles and deduced it must be because the hardware is so similar. Thanks for correcting me. Still I do believe a closed system is favorable for the user as long as the one who controls the system does a great job. I am thinking of a windows were one can only install software which does not mess up the system resources, or causes other harm. It would reduce the PC troubles for inexperienced users dramatically.
