Yin and Yang is the concept of duality forming a whole. In our every day lives, we see many examples of Yin and Yang before us. Think of pairings like night and day, or female and male. Diving deeper into the principles of Yin and Yang in Taoism, you'll find that neither are absolute, nor are they static, and that the summation of Yin and Yang form a whole and that their balance can be skewed due to outside influences. Over thousands of years a LOT of things have been sorted and grouped under Yin and Yang classification systems. You know where I'm going with this. When it comes to smartphones, there has been no example more clear in demonstrating Yin and Yang then that of Apple's iPhone and Research in Motion's traditional (non-touch) BlackBerry.
