You know, we started obviously in Apple using the iPad well before it was launched. Of course, we had our shades pulled and everything so nobody could see us. What I started noticing about my own personal behavior, it quickly became 80 to 90 percent of my consumption and work was done on the iPad. – Tim Cook
It gets overstated but it's worth nothing again and again. Apple wants to make the tablet a computer. Amazon wants to make the tablet a consumption device.
It all depends on your needs.
