对问题3加一个细节和修正： 3.In this book, you carried a lengthy critical commentary on CUI, but CUI is already taking the leading role in today’s computer system，for example the apple-initiated touch screen CUI on mobile devices. How do you decipher this kind of situation?
我也来补充两个问题吧： 1. As we know, Android is a Linux-based operating system for mobile devices,which is also one of the dominant OS in this fast-growing mobile industry, do you think it will become the "next Linux" in this area? 2. Can the fact of Linux-oriented initiatives becoming more and more in mobile area mean that Linux will become the key computing technology in the mobile industry?
